bushing

What you should know about bushings

If you are in the market for a casing, there are a few things you should know before buying. First, a bushing is a mechanical part with a rotating or sliding shaft part. You can find them in almost all industrial applications due to their excellent load-carrying capacity and anti-friction properties. They are especially important in construction, mining, agriculture, hydropower, material handling, and more.

Casing application

The casing market is mainly driven by the growth of the power generation industry. The increasing electrification of Asia Pacific and the deployment of renewable energy in countries such as Saudi Arabia and the UAE are driving the demand for distribution transformer bushings. In addition, the demand for bushings in Western Europe is also likely to increase with the spread of renewable energy and the installation of electric vehicle charging infrastructure. However, the market in Asia Pacific is expected to remain small compared to the rest of the world.
Although bushings are relatively expensive, they are very durable and cost-effective. Furthermore, bushings have a variety of applications, making them an important component in power transformers. For example, power transformers often use bushings to achieve relative movement by sliding or rolling. The vehicle suspension system also uses rubber bushings for a smooth ride and rotating bushings for machine-related operations. They require precision machined parts and are especially useful in applications where high loads and friction must be controlled. Also, plastic bushings are used for wheels in dry kilns, where lubrication is often troublesome.
Transformers require constant monitoring, which is one of the reasons bushings are so important in power transformers. Any failure of these components could result in the total loss of the transformer and all surrounding equipment. To maintain high system reliability, utilities must monitor insulation in and around bushings, especially if transformers have been in use for decades. Some utilities have made monitoring the condition of their transformers an important part of their smart grid plans.

Material

The core of the dry casing has many material interfaces. The discharge most likely originates near the edges of the foils and can cause electrical tree growth or breakdown between adjacent foils. Several studies have investigated interfacial effects in composite insulating materials and concluded that the conditions under which the interface occurs is a key factor in determining the growth of electrical trees. This study found that material type and interface conditions are the two most important factors for the growth of electrical trees.
Bushings can be made of many different materials, depending on their purpose. The main purpose of the bushing is to support the assembly while protecting it. They must be stiff enough to support the load placed on them, and flexible enough to protect the shaft. Since the shaft is usually not centered on the bushing during rotation, the bushing must be durable enough to carry the load while still protecting the shaft. Here are several materials used for bushings:
A stabilizer bar assembly is a good example of pre-assembly. This pre-assembly enables the vehicle assembly plant to receive components ready for vehicle assembly. The prior art requires the vehicle assembly plant to separate the bushing from the stabilizer bar. However, the present invention eliminates this step and provides a mechanically rigid stabilizer bar assembly. It is designed to prevent audible squeals and improve vehicle performance and handling.
Hardened steel bushings are ideal for pivot and low speed applications. They are made of high carbon steel and fully hardened to 56-62 HRC. Bronze bushings require daily or weekly lubrication but are more expensive than plastic bushings. Plastic bushings are low cost, low maintenance, self lubricating and do not require regular lubrication. These are also suitable for applications with hard to reach parts.
bushing

application

Bushings have many applications in various industries. Most of the time, it is used for drilling. Its excellent chemical and mechanical properties can be used to protect various equipment. These components are versatile and available in a variety of materials. All sleeves are packaged according to national and international standards. They are used in many industrial processes from construction to drilling. Some application examples are listed below.The component 10 may contain a tank for a liquid such as fuel, and the object 12 may be made of fiber reinforced composite material. Sleeve assembly 16 is configured to ground component 10 and object 12 . It may be a bulkhead isolator 40 used to isolate electrical charges in aircraft hydraulic lines. Bushing assembly 16 is one of many possible uses for the bushing assembly. The following examples illustrate various applications of bushing assemblies.
Bearings are devices used to reduce friction between moving surfaces. They are a good choice for many applications as they are maintenance free and extend the life of machine components. They can be used in a variety of applications and are often used with plastic and metal materials. For example, Daikin offers bronze and brass bushings. Bushings have many other uses, but they are most commonly used in machines, especially when used in low-load environments.
The most common application for bushings is drilling. Swivel bushings can be used in almost any drilling application. For more complex applications, CZPT’s engineering department can create special designs to your specifications. The applications of bushings in machining centers are endless. By providing a smooth, reliable interface, bushings are an excellent choice for precision machining. They can also provide current paths.

Cost

When you have a vehicle that needs a bushing replacement, you may be wondering about the cost of a bushing replacement. The fact is, the cost of a bushing replacement will vary widely, depending on the specific car model. Some cars cost as little as $5, while other vehicles can cost up to $300. The replacement of a control arm bushing may not cost that much, but it’s important to know that it’s a relatively expensive part to replace.
Most mechanics charge around $375 for a job that involves replacing the bushing in a control arm. However, this price range can vary significantly, depending on whether the mechanic uses OE or aftermarket parts. In any case, the cost of labor is typically included in the price. Some mechanics may even include a labor charge, which is an additional cost. In general, however, the cost of a control arm bushing replacement is comparable to the cost of replacing a single bushing.
Control arm bushings are made of two metal cylinders secured together by a thick layer of rubber. Over time, these parts can deteriorate due to accidents, potholes, and off-roading. For this reason, it is important to replace them as soon as possible. Bushing replacement can save you money in the long run, and it’s important to have your vehicle repaired as soon as possible. If your control arm bushing is showing signs of wear, you should have it replaced before it becomes completely useless.
If you have decided to replace your suspension bushing yourself, the cost will be considerably lower than you would spend on the replacement of other components. If you have a mechanically-inclined mechanic, you can do it yourself. The parts and labour are reasonably cheap, but the most expensive part is the labor. Because it requires disassembling the wheel and suspension and installing a new bushing, it is important to have a mechanic who has a good understanding of vehicle mechanicry. The cost for control arm bushing replacement is between $20 and $80 per bushing, and a set of four costs approximately $300.

What is a slewing ring, and how is it used in mechanical systems?

A slewing ring, also known as a slewing bearing or turntable bearing, is a specialized type of rolling element bearing that enables rotational movement between two components. It consists of an inner ring, an outer ring, rolling elements (such as balls or rollers), and often a gear mechanism. Slewing rings are used in mechanical systems where there is a need for smooth and controlled rotation. Here’s a detailed explanation of what a slewing ring is and how it is used:

  • Structure and Components: A slewing ring typically has a large diameter compared to its thickness, allowing it to support axial, radial, and moment loads. The inner and outer rings have raceways that the rolling elements move along. The rolling elements, which can be balls or rollers, distribute the load and facilitate smooth rotation. In some cases, a gear mechanism is integrated into the slewing ring, allowing it to act as a rotational drive system.
  • Rotational Movement: The primary function of a slewing ring is to enable rotational movement between two components. It provides a stable and low-friction interface that allows one component to rotate relative to the other. The rolling elements within the raceways minimize friction and distribute the load evenly, resulting in smooth and controlled rotation. Slewing rings can support both continuous rotation and intermittent or oscillating movement, depending on the application requirements.
  • Load Support: Slewing rings are designed to support various types of loads. They can handle axial loads, which are forces acting parallel to the axis of rotation, as well as radial loads, which are forces acting perpendicular to the axis of rotation. Additionally, slewing rings can accommodate moment loads, which are a combination of axial and radial loads that create bending or twisting forces. The load-carrying capacity of a slewing ring depends on factors such as its size, design, and choice of rolling elements.
  • Applications: Slewing rings find applications in a wide range of mechanical systems across different industries. Some common uses include:

Types of Ball Bearings

Modern ball bearing configurations have different materials and geometries to meet the demands of different working environments and applications. There are different types of ball bearings: single row deep groove, double-row deep groove, angular contact ball bearing, thrust, and self-aligning. Let us look at the differences between each type and learn why they are important for various purposes. Listed below are some of the most common types of ball bearings.

Miniature bearings

Although miniature ball bearings are a popular choice for small mechanical components, they are not without their challenges. They must be properly lubricated and stored in clean rooms. A strand of hair could ruin a miniature bearing. Fortunately, manufacturers offer lubrication services and a “Clean Room” for customers to store their miniature bearings safely. Read on to learn more about these small bearings and how they can help you.
The size of a miniature ball bearing can vary significantly, but most types of these devices are available in sizes ranging from.040 inch to one eighth of an inch. Whether you need a small ball bearing for a miniature car or a tiny instrument, a miniature bearing can save space while still offering high performance. Many of these bearings are shielded to prevent dirt from entering and leakage of lubricant. They can be flanged or unflanged, and some miniature ball bearings have extended inner rings that are designed for easy plate mounting.
Miniature ball bearings are commonly made from stainless steel or chrome steel. Both metals have their advantages. Stainless steel is the most popular material for ball bearings, which allows for a high load capacity while being quiet. Because stainless steel is relatively inexpensive, many small instrument bearings are made entirely of stainless steel. The difference in price is minimal, as the amount of steel is relatively small. Stainless steel miniature bearings are the smallest and lightest of all types of miniature ball bearings.

Self-aligning ball bearings

In the simplest terms, self-aligning ball bearings are ball bearings with flex shafts. If you’re looking for a ball bearing with a high degree of precision, you’ll want to choose one with a flex shaft, which means it can adjust to the proper orientation of the bearing’s flex shaft. Ball bearings with flex shafts are also recommended. But, what are these bearings?
Self-aligning ball bearings are made with two rows of balls and a common sphered raceway on the outer ring. As a result, they can accommodate small errors in shaft alignment and mounting. The CZPT brand is especially suitable for high-speed applications requiring greater running accuracy. The self-alignment mechanism is enabled by the fact that the balls are placed in two rows on either side of the sphered raceway in the outer ring. These two rows of balls also promote reduced friction and wear.
Another type of self-aligning ball bearings is a double-row design. They feature a common sphered raceway on the outer ring, a hollow spherical ring, and a cage that rotates relative to it. A self-aligning ball bearing is used in applications where shaft misalignment is a problem, such as conveying equipment. They are also used in simple woodworking machinery and ventilators.

Ceramic ball bearings

Ceramic ball bearings have several advantages over steel or metal bearings. These include increased acceleration capability, reduced friction, improved wear-resistance, and higher speeds. The United States holds the leading position in the global ceramic ball bearings market thanks to a rebounding motor vehicle production and healthy fixed investment environment. In the United States, there are three primary markets for ceramic ball bearings: healthcare, automotive, and aerospace. Here are the main benefits of ceramic ball bearings:
Hybrid ball bearings are also available. Hybrid bearings feature traditional metal rings and silicon nitride (ceramic) balls. Hybrid bearings offer important performance advantages over all-steel bearings, and they are more affordable. However, full ceramic ball bearings have all ceramic parts, and are best suited for machines that require high precision. These types of bearings also resist corrosion and wear.
Compared to steel ball bearings, ceramic balls are lighter than steel. They are also less dense, which means less friction and therefore less heat. Additionally, ceramic balls operate at higher speeds than steel balls, which increases their durability and longevity. But they are still not as strong as steel bearings. And because of their reduced density, they are much cheaper to manufacture. Therefore, they are an excellent choice for many applications. You can expect them to last much longer than steel bearings.

Steel carbon ball bearings

High precision G25 ball bearings are made of the highest grade chrome steel and hot forged from bar stock. Statistical process control and exacting atmospheres help ensure uniform hardness and microstructure. Moreover, these bearings are of the highest quality, with fine surface finish and a tight tolerance. This makes them the most widely used and reliable choice for industrial and automotive applications. However, there are some considerations that should be taken into account before acquiring a steel carbon ball bearing.
Generally, AFBMA grade 200 is the standard hardness specification for this material. AFBMA grade 100 can also be obtained with great difficulty. Despite the high hardness of steel carbon ball bearings, their outer surface is just a thin hardened shell, so a special micro hardness test is needed to evaluate them. In addition to the hardness, steel balls are easily machined and ground. Some manufacturers even offer stainless steel ball bearings and ball sets.
Another factor that makes steel carbon ball bearings so valuable is their precision. They can give precise measurements, which makes them ideal for low and medium-speed applications. Due to their high precision and durability, steel carbon ball bearings can be used in many applications, from conveyor machines to roller skates. However, you should be aware that the material used to produce these bearings is not suitable for applications in which they are exposed to water and gases. Further, they are also noisy and heavy, and must be installed properly in a manufacturing environment.

Stainless steel ball bearings

bearing
Stainless steel ball bearings are made from a high-quality type of stainless steel, 440C, which offers optimal corrosion and abrasion resistance. These bearings are also durable and rust-free, and are suitable for a variety of applications. Among others, stainless steel ball bearings are used in beverage and food processing plants, pharmaceuticals, pulp and paper mills, marine environments, and freezers.
Stainless steel bearings are available in various grades. For example, AISI 440C offers corrosion resistance, while the DD400 is specifically designed for marine applications. Both types of stainless steel are available in different forms, including open, shielded, and sealed. Stainless steel ball bearings can also be custom-made, as BL is known for producing customized bearings. There are also other materials that are available.
AISI type 316 stainless steel balls are ideal for marine applications and food processing. They have excellent resistance to most organic materials and are also used in medical devices and dispenser pumps. They are also strong enough to resist many petroleum products and are widely used in medical equipment and cosmetic applications. In addition, stainless steel balls can be plated to provide an additional layer of protection against chemicals. To understand how they differ, let’s take a look at some common types of stainless steel ball bearings.

Stainless steel

Stainless steel ball bearings can be used in various applications. Besides being corrosion resistant, they also last longer thanks to the Molded-Oil lubrication technology. Stainless steel ball bearings are clean units, which saves time and money in terms of maintenance, replacement, and downtime. But what are the advantages of stainless steel ball bearings? Let us discuss these benefits. Also, we’ll discuss their advantages and disadvantages.
Stainless steel ball bearings offer notable advantages, including corrosion resistance, increased strength, and improved stability under high temperatures. These qualities make them the ideal choice for special circumstances and demanding environments. However, you should be careful when choosing stainless steel bearings. There are several different types of stainless steel. Here’s a brief look at what makes them the best choice. And remember: Stainless steels are also recyclable. In fact, they can be recycled indefinitely.
They’re made from chrome alloy electric furnace steel, which is hardened for optimum service life and strength. They have the highest surface finish and dimensional accuracy. Advanced heat-treating processes increase their strength and anti-cracking abilities. And thanks to their unique materials, they’re corrosion-resistant. As a result, they’re more durable than other types of bearings. And since they’re made with a high-quality steel, you’ll save money in the long run.

Plastic ball bearings

Plastic ball bearings were developed to meet the specific needs of applications where standard steel bearings would fail. Steel and 440C stainless steel are both susceptible to rusting when exposed to water, making them poor choices for applications involving food processing, swimming pools, and medical equipment. In addition to this, the plastic material is able to dampen vibrations and make the bearing virtually silent. Here’s what makes plastic ball bearings so great for these applications.
Plastic ball bearings are lightweight, corrosion-resistant, and offer a long service life. In addition to their low price, they can be easily cleaned and are incredibly durable. Motion plastics specialist igus has recently expanded its range of xiros polymer grooved ball bearings. These bearings are also FDA-compliant, lubricant-free, electrically insulating, and resistant to both temperature and media.
Plastic bearings are often mounted into other components like wheels, pulleys, and housings. In this way, the inner ring is essentially a profile of the pulley’s profile, and the outer ring is a shaft or fixing clip. The result is seamless integration of the bearing and the surrounding parts, which reduces the overall assembly time and costs. You can also use multiple plastic ball bearings in one application for more options.

Product Process

 

SLEWING BEARING RINGS

Rings are mainly made of 50Mn carbon steel or alloy steels such as 42CrMo4 and the choice of material depends on the required mechanical properties. Alloy steels are often used for heavy-duty applications. Their structural characteristics mean that heat treatments are more effective and greater surface hardness can be obtained than with carbon steels. Stainless steels such as AISI420 or AISI440C can be used for applications where corrosion resistance is required.

RACEWAYS

The raceways are heat-treated by induction in order to achieve a maximum surface hardness of 62 HRC for carbon or alloy steels, or 58 HRC for stainless steels. The hardening depth can vary depending on the type of steel. Hardening treatment is essential to allow the slewing coupling to support the heavy-duty loads it is exposed to in its intended application.

ROTATING ELEMENTS

The rotating elements used in slewing bearings may be balls or cylindrical rollers; both are typically made of 100Cr6 steel but other materials such as ceramic (zirconium oxide ZrO2 or silicon nitride Si3N4) or stainless steel (AISI440C) can be used. Rolling elements with different materials, sizes and precision grades are selected depending on the desired results.

CAGES OR SPACERS

Slewing bearing clearance plays a crucial role and is defined and optimised according to the application and performance to be achieved.
Cages or spacers made of different materials can be used to separate rolling elements, balls or rollers, depending on the loads and speeds required by the specific application.

PROTECTIONS

Special sliding seals are fitted between the inner and outer ring to protect the slewing bearing against the ingress of debris, dust or water particles that could affect its operation. The material used for seals is typically NBR rubber, but different materials can be chosen for specific applications.

LUBRICANT

The lubricant is another very important factor to ensure effective operation of the base bearing. The type of lubricant, quantity, quality, lubrication intervals, number and position of greasing points are determined according to the performance required of the slewing bearing and any specific customer requirements.

GEARED RINGS

Slewing bearing rings can be spur-gear or, more rarely, helical-gear. The gear module is sized and selected according to the application requirements.
Typically, the gearing is soft, i.e. untreated – the maximum hardness of untreated gears is 30 HRC for 42CrMo4. When service conditions require it, the gear surface can be induction-hardened to achieve a surface hardness of 60 HRC. Gear hardening is required when at least 1 of the following variables must be satisfied:

  • high rolling torque
  •  
  • high rotating speed
  •  
  • unfavourable environmental conditions, presence of CHINAMFG elements
  •  
  • maximum tooth lifetime

How do slewing rings contribute to precise and controlled motion in machinery?

Slewing rings play a crucial role in enabling precise and controlled motion in machinery. Their design and functionality contribute to achieving accurate positioning, smooth rotation, and controlled movement. Here’s a detailed explanation of how slewing rings contribute to precise and controlled motion:

  • Precision Engineering: Slewing rings are meticulously engineered to provide high precision in motion control. The manufacturing processes involve tight tolerances and precise machining to ensure accurate dimensions and alignment of the rolling elements and raceways. This precision engineering minimizes any deviations or errors in motion, allowing for precise positioning and controlled movement.
  • Low Friction and Smooth Rotation: Slewing rings are designed to minimize friction and enable smooth rotation. The rolling elements, whether balls or rollers, are precisely positioned and guided within the raceways of the slewing ring. This design ensures that the rolling elements make contact with the raceways at specific angles, reducing friction during rotation. The low-friction characteristics allow for smooth and controlled motion, enabling precise positioning without undue resistance or jerky movements.
  • Integrated Gear Mechanism: Many slewing rings are equipped with an integrated gear mechanism. The gear teeth on the inner or outer ring of the slewing ring engage with external gears or pinions, providing a means to transmit torque and control rotational motion. The gear mechanism allows for precise and controlled movement, enabling operators or automated systems to achieve accurate positioning and controlled rotation at desired speeds.
  • Backlash Control: Backlash refers to the slight play or clearance between mating gears or components. Slewing rings are designed to minimize backlash, particularly in applications that require precise motion control. By reducing or eliminating backlash, slewing rings ensure that there is minimal lost motion or error when initiating rotational movement or changing direction. This feature contributes to improved accuracy and controlled motion.
  • Stiffness and Rigidity: Slewing rings are designed to provide high stiffness and rigidity, minimizing deflection or deformation during operation. This characteristic is especially important in applications where precise and controlled motion is required. The high stiffness of slewing rings ensures that the applied forces and torques are efficiently transmitted, allowing for accurate positioning and controlled motion without significant distortion or flexing.
  • Positioning Sensors and Feedback Systems: In conjunction with slewing rings, machinery often incorporates positioning sensors and feedback systems. These sensors and systems provide real-time data on the position, speed, and rotation of the slewing ring. By continuously monitoring and adjusting the motion based on the feedback, precise and controlled movement can be achieved, enabling accurate positioning and motion control.

Overall, slewing rings contribute to precise and controlled motion in machinery through their precision engineering, low friction, integrated gear mechanisms, backlash control, stiffness, and compatibility with positioning sensors and feedback systems. These features ensure accurate positioning, smooth rotation, and controlled movement, making slewing rings essential components for applications that require precise motion control in various industries such as construction, material handling, robotics, and manufacturing.

What are the signs that indicate a need for slewing ring replacement or maintenance, and how can they be diagnosed?

When it comes to slewing rings, certain signs indicate the need for replacement or maintenance to ensure optimal performance and prevent potential failures. Here’s a detailed explanation of the signs that indicate a need for slewing ring replacement or maintenance, along with methods for diagnosis:

  • Unusual Noise: Unusual noises, such as grinding, clicking, or squealing sounds, during the operation of rotating systems may indicate a problem with the slewing ring. These noises can be caused by worn-out or damaged rolling elements, insufficient lubrication, misalignment, or other issues. Diagnosis involves conducting a thorough inspection of the slewing ring and its components to identify the source of the noise and determine the appropriate course of action.
  • Abnormal Vibration: Excessive vibration during the operation of rotating systems can be a warning sign of a faulty slewing ring. It may indicate misalignment, imbalanced loads, damaged rolling elements, or worn-out bearings. Vibration analysis techniques, such as using vibration sensors or analyzers, can help diagnose the source and severity of the vibration. Based on the analysis results, appropriate maintenance or replacement actions can be taken.
  • Irregular Movement: Any irregular movement or jerking motion of the rotating system can be an indication of a problem with the slewing ring. It may be caused by damaged or worn-out teeth on the slewing ring, misalignment, or inadequate lubrication. Visual observation of the system’s movement during operation can help identify any irregularities. Additionally, conducting a detailed inspection of the slewing ring and its teeth can provide further insight into the issue.
  • Increased Friction: If there is a noticeable increase in friction or resistance during the rotation of the system, it could be a sign of a problem with the slewing ring. This may be due to insufficient or contaminated lubrication, damaged rolling elements, or misalignment. Diagnosis involves checking the lubrication levels and quality, inspecting the rolling elements for signs of damage, and verifying the alignment of the slewing ring.
  • Uneven or Excessive Wear: Visual inspection of the slewing ring can reveal signs of uneven or excessive wear. This can manifest as worn-out or pitted rolling elements, damaged or missing teeth, or abnormal wear patterns on the raceways. Regular inspections and comparing the current condition with the manufacturer’s specifications or previous inspection records can help diagnose the level of wear and determine if maintenance or replacement is necessary.
  • Leakage or Contamination: Leakage of lubricant or the presence of contaminants, such as dirt, water, or debris, in the slewing ring assembly can be indicative of a problem. It may lead to inadequate lubrication, accelerated wear, or corrosion. Visual inspection of the slewing ring and any associated seals or gaskets can help identify any signs of leakage or contamination. Addressing the source of the leakage and ensuring proper sealing is essential to maintain the integrity and performance of the slewing ring.
  • Reduced Load-Carrying Capacity: If the rotating system experiences difficulty in handling its intended loads or shows signs of decreased load-carrying capacity, it may indicate an issue with the slewing ring. Factors such as worn-out rolling elements, damaged raceways, or misalignment can contribute to the reduction in load-carrying capacity. Performance testing and comparing the system’s current capabilities with its original specifications can help diagnose any loss in load-carrying capacity.

In summary, signs that indicate a need for slewing ring replacement or maintenance include unusual noise, abnormal vibration, irregular movement, increased friction, uneven or excessive wear, leakage or contamination, and reduced load-carrying capacity. These signs can be diagnosed through visual inspections, vibration analysis, performance testing, and comparing the observed conditions with the manufacturer’s specifications. Early detection and timely maintenance or replacement of the slewing ring can prevent further damage, ensure safe operation, and extend the lifespan of the rotating system.

Product Process

 

SLEWING BEARING RINGS

Rings are mainly made of 50Mn carbon steel or alloy steels such as 42CrMo4 and the choice of material depends on the required mechanical properties. Alloy steels are often used for heavy-duty applications. Their structural characteristics mean that heat treatments are more effective and greater surface hardness can be obtained than with carbon steels. Stainless steels such as AISI420 or AISI440C can be used for applications where corrosion resistance is required.

RACEWAYS

The raceways are heat-treated by induction in order to achieve a maximum surface hardness of 62 HRC for carbon or alloy steels, or 58 HRC for stainless steels. The hardening depth can vary depending on the type of steel. Hardening treatment is essential to allow the slewing coupling to support the heavy-duty loads it is exposed to in its intended application.

ROTATING ELEMENTS

The rotating elements used in slewing bearings may be balls or cylindrical rollers; both are typically made of 100Cr6 steel but other materials such as ceramic (zirconium oxide ZrO2 or silicon nitride Si3N4) or stainless steel (AISI440C) can be used. Rolling elements with different materials, sizes and precision grades are selected depending on the desired results.

CAGES OR SPACERS

Slewing bearing clearance plays a crucial role and is defined and optimised according to the application and performance to be achieved.
Cages or spacers made of different materials can be used to separate rolling elements, balls or rollers, depending on the loads and speeds required by the specific application.

PROTECTIONS

Special sliding seals are fitted between the inner and outer ring to protect the slewing bearing against the ingress of debris, dust or water particles that could affect its operation. The material used for seals is typically NBR rubber, but different materials can be chosen for specific applications.

LUBRICANT

The lubricant is another very important factor to ensure effective operation of the base bearing. The type of lubricant, quantity, quality, lubrication intervals, number and position of greasing points are determined according to the performance required of the slewing bearing and any specific customer requirements.

GEARED RINGS

Slewing bearing rings can be spur-gear or, more rarely, helical-gear. The gear module is sized and selected according to the application requirements.
Typically, the gearing is soft, i.e. untreated – the maximum hardness of untreated gears is 30 HRC for 42CrMo4. When service conditions require it, the gear surface can be induction-hardened to achieve a surface hardness of 60 HRC. Gear hardening is required when at least 1 of the following variables must be satisfied:

  • high rolling torque
  •  
  • high rotating speed
  •  
  • unfavourable environmental conditions, presence of CHINAMFG elements
  •  
  • maximum tooth lifetime

Can you describe the factors to consider when selecting slewing rings for specific applications?

When selecting slewing rings for specific applications, several factors need to be considered to ensure optimal performance and reliability. Here’s a detailed description of the factors to consider:

  • Load Requirements: The load capacity of the slewing ring should match the anticipated loads in the application. Consider both the maximum static load (weight of the structure or equipment) and dynamic load (forces during operation). It is crucial to analyze the load distribution, including axial, radial, and moment loads, and select a slewing ring with sufficient load-carrying capacity to handle these loads.
  • Space Limitations: Evaluate the available space for the installation of the slewing ring. Consider the diameter, height, and width of the slewing ring to ensure it fits within the space constraints of the application. It is essential to consider both the external dimensions of the slewing ring and the required clearance for rotation.
  • Rotational Speed: Determine the required rotational speed of the slewing ring. Consider the application’s operating speed and any specific speed limitations. The slewing ring should be selected to accommodate the rotational speed requirements while maintaining smooth and efficient operation.
  • Environmental Conditions: Evaluate the operating environment of the application. Factors such as temperature, humidity, dust, water exposure, chemicals, and corrosive elements should be considered. Choose a slewing ring with appropriate sealing systems, corrosion-resistant materials, and lubrication options to withstand the specific environmental conditions.
  • Accuracy and Positioning: Some applications require precise positioning and rotational accuracy. Determine the required level of accuracy and select a slewing ring that provides the necessary precision. Factors such as gear mechanism, backlash control, and manufacturing tolerances contribute to the accuracy of the slewing ring.
  • Operating Conditions: Consider the overall operating conditions of the application, including factors such as shock and vibration levels, duty cycle, continuous or intermittent operation, and expected service life. The slewing ring should be designed to withstand the anticipated operating conditions and provide reliable performance over the desired lifespan.
