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:
  • Construction and Cranes: Slewing rings are extensively used in construction machinery, cranes, and mobile equipment. They enable 360-degree rotation of the boom or jib, allowing for efficient material handling and positioning.
  • Wind Turbines: Slewing rings are crucial components in wind turbine systems. They support the rotor, allowing it to rotate according to wind direction, and provide a connection between the rotor and the nacelle, enabling yaw movement.
  • Industrial Equipment: Slewing rings are utilized in various industrial equipment, including indexing tables, turntables, robotic arms, and packaging machinery. They facilitate precise and controlled rotation in these applications.
  • Transportation and Automotive: Slewing rings are employed in transportation and automotive applications, such as vehicle cranes, aerial platforms, and rotating platforms for heavy-duty vehicles. They enable safe and smooth rotation in these specialized systems.

Understanding the Different Types of Bearings

When you are looking for a bearing, you have many options to choose from. This article will explain the various types, functions, and working principles of different types of bearings. Once you understand the basic components, you can make an informed decision about which one to buy. Here’s an overview of some of the most common types. Learn more about each type below! Read on to learn about the differences between these different types of bearings! Posted in Articles

Functions

Bearings serve as an integral part of a mechanical device. These devices help transfer torque from one part of a structure to another. These mechanisms increase the efficiency of a shaft by increasing its life. However, the functions of bearings depend on the application of the structure. Among other functions, bearings provide support to shafts. Anti-friction bearings come in two types: ball and roller bearings. These components have line and point contact, which is the most common type. Archimedes’s principle states that the force is equal to the weight of the fluid that is being displaced. Bearings can transfer lateral loads to a substructure.
A bearing has two primary functions. The first is to prevent direct metal-to-metal contact. A bearing prevents friction, heat generation, and wear and tear of components. A bearing also reduces energy consumption. Its other purpose is to guide and support a rotating body. In addition to these functions, bearings can also reduce wear and tear on a machine. As a result, they are among the most widely used machines in the world.
Seals are a major component of a bearing. They prevent foreign materials from entering and lubricating the moving parts. The design of seal lips determines their effectiveness. Fuel economy regulations and CO2 emissions regulations are pushing the demand for low-friction bearings. However, high-performance seals do not always provide high-performance. As a result, current estimations of the friction in bearings depend on trial and error methods.
Another important function of bearings is that they transfer the load of a rotating component to its housing. This load can be axial or radial. Bearings also limit movement to predefined directions. Some types of rolling element bearings have balls or cylinders inside. These bearings are less frictional than sliding ones, thus they allow parts to move freely during rotation. These parts can then be used for various applications. So, bearings are an integral part of machines.

Types

The most common type of bearing is a plain bearing. It uses surfaces in rubbing contact to transmit movement from one part to another. These bearings may be discrete or may consist of a hole in a metal sleeve or a planar surface bearing another part. Some plain bearings are flanged, while others are made of a sleeve with a flange at one end. These bearings often give acceptable accuracy and life, but they are expensive and cannot be used in large scale applications.
Radial bearings are used when there is a need for high-speed or corrosive parts. This type of bearing also serves as a support in an intermediate situation. Its two components are called the base and the cover. The base and cover are connected and are arranged parallel to the main axis. This type of bearing is used in steady-state and axial motion applications. The radial bearings are also used when the shafts are long.
Angular contact bearings are another type of bearing. These are easy to install and require minimal maintenance. Their races are displaced along the axis. They are also better at handling axial loads and transferring them to the housing. These types of bearings are commonly used in pumps, automobiles, and high-speed applications. If you are looking for an affordable, reliable bearing, look no further than the angular contact bearing.
Another type of bearing is a self-lubricating bushing. These are lightweight and wear-resistant. Unlike the other types of bearing, they do not require any lubrication or maintenance. In fact, some are completely maintenance-free. But if you’re worried about maintenance, this type of bearing may be a good choice. There are many benefits of using self-lubricating bushings. It is also a good option for applications where your machine is exposed to extreme temperatures.

Working principle

bearing
A bearing has two primary functions: support and load transfer. In engineering applications, the bearing tends to push the load in the direction of the shaft. A radial load pushes the bearing downward and a thrust load pushes it sideways. Both types of load transfer are important in a variety of applications. The working principle of each type is described below. Listed below are the main uses for each type of bearing.
A plain bearing uses a PTFE liner on the interface of two moving parts. The PTFE liner acts as a lubricant and may be filtered to alter its friction. The journal bearing uses the motion of the journal to force fluid into the gap between two moving parts. This results in a small amount of play in the bearing. This play is acceptable for most applications. A ball bearing may have a maximum play of 2 mm for a ten-millimeter shaft.
The primary function of a bearing is to assist in rotation and to reduce mechanical friction between the two objects. A bearing may be installed as a separate device or as an integral part of a machine. For more complex applications, bearings are very precise components requiring the highest standards of technology. For this reason, it is important to understand the working principle of bearings. The next time you need to lift or slide a heavy object, consider a bearing.
Ball bearings are a common type of ball bearing and can be found in industrial machinery and automobiles. Their unique structure helps them support less weight. This is because they are comprised of two rings – an inner race and an outer race. The balls themselves have a small area of contact and transfer axial loads in one direction. A cage surrounds the balls and prevents them from colliding. This makes ball bearings a popular choice for many applications.

Sealing system

A bearing’s seals are vital for the operation of rolling and rotating components. These systems enable rotation and linear movement while limiting friction and dispersing stress. Without the proper seals, these components could face catastrophic failure. In addition to protecting the bearing from external forces, seals help retain lubricant inside the system and prevent harmful particles from entering the gap. A seal’s lubrication helps prevent the onset of mechanical damage and prolongs the life of the bearing.
A bearing seal is made up of two parts: the inner sealing element and the outer sealing element. A passageway runs through the bearing assembly to the outer seal element. A hydraulic press or pneumatic jack is recommended for installing the seal. These tools are effective in reducing deformation and improving seal installation quality. When fitting the seal, ensure that the tool does not hit the seal directly. A proper adopter will distribute the load uniformly across the seal.
The seal’s efficiency depends on its gap. A four-inch shaft seal can flow 0.5 standard cubic feet per minute. A seal’s efficiency is highly dependent on the gap size. The gap size is a cube of the flow through the system. A smaller gap size allows high flow and pressure but less leakage. If both surfaces of the seal have similar pressures and flow rates, the seal is efficient. However, a small gap reduces the pressures and reduces wear.
Mechanical seals have numerous advantages, including their ability to protect against contaminants and splashing liquids. Labyrinth seals are the first line of defense against leaks. They operate without friction. Their high level of sealing efficiency helps ensure that the bearing remains operational for long. This type of seal is made from metal plates and is designed for a wide temperature range and misalignment. Its advantages include being easy to install and offering 100% sealing efficiency.

Maintenance

bearing
Bearing maintenance is critical to ensuring that your bearings keep operating at their peak performance. Proper maintenance will improve bearing life, reduce downtime and increase productivity while reducing costs. Here is an 8-point checklist to optimize your bearings and make them last longer. To optimize their performance, you should follow these steps regularly. In case a bearing does not last long, you should replace it as soon as possible. Listed below are some tips to ensure proper maintenance.
The first step is to determine how often your bearings require lubrication. Some manufacturers recommend that you lubricate them weekly, but this can do more harm than good. Instead, use ultrasound to measure the level of friction and trend its levels. This way, you will know exactly when to grease your bearings. It’s also important to check how often they should be inspected and calibrated. A professional can provide guidance on proper maintenance.
Next, inspect your bearings for cracks and scratches. You should never install a bearing that has been dropped or scratched. Even a small crack will affect the performance of the bearing and could lead to its premature failure. A proper alignment is essential for the bearing to function properly. Make sure you have the correct tools to perform this task. These tools can help you reduce manual work and promote safe bearing maintenance. You should also ensure that the shaft and housing are clean and undamaged.
Proper maintenance can prolong bearing service life. Proper lubrication, mounting, inspection, basic condition monitoring, and dismounting can extend their life. Proper maintenance extends their lifespan and improves plant productivity. While bearings are essential for machinery, you should make sure you follow the proper safety procedures every time you work with them. These tips will also help prevent accidents and maintain your machine’s efficiency. Once you’ve followed these guidelines, you can safely inspect your bearings and ensure that they’re operating at their optimum capacity.

By providing a stable and reliable foundation, slewing rings enable the integration of multiple components, enhancing the versatility and adaptability of the overall system.
  • Customization and Specialized Designs: Slewing rings can be customized and designed to meet specific application requirements. Manufacturers can tailor slewing rings to accommodate specific load capacities, dimensions, mounting arrangements, sealing systems, or environmental conditions. This customization allows for the adaptation of slewing rings to diverse settings, ensuring optimal performance and functionality.
  • Integration with Control Systems: Slewing rings can be integrated with electronic or computer-controlled components, such as sensors, actuators, and control systems. This integration enables precise control, automation, and synchronization of rotating systems. By incorporating advanced control features, slewing rings can adapt to dynamic operating conditions, optimize performance, and support advanced functionalities, such as coordinated motion, precision positioning, or remote monitoring.

In summary, slewing rings contribute to the adaptability and versatility of rotating systems by enabling 360-degree rotation, providing high load-bearing capacity, offering a compact design, supporting versatile mounting options, accommodating multiple components, allowing customization, and facilitating integration with control systems. These characteristics make slewing rings suitable for a wide range of applications and settings, enhancing the versatility and adaptability of rotating systems in industries such as construction, manufacturing, transportation, renewable energy, and many others.

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.

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 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:
  • Construction and Cranes: Slewing rings are extensively used in construction machinery, cranes, and mobile equipment. They enable 360-degree rotation of the boom or jib, allowing for efficient material handling and positioning.
  • Wind Turbines: Slewing rings are crucial components in wind turbine systems. They support the rotor, allowing it to rotate according to wind direction, and provide a connection between the rotor and the nacelle, enabling yaw movement.
  • Industrial Equipment: Slewing rings are utilized in various industrial equipment, including indexing tables, turntables, robotic arms, and packaging machinery. They facilitate precise and controlled rotation in these applications.
  • Transportation and Automotive: Slewing rings are employed in transportation and automotive applications, such as vehicle cranes, aerial platforms, and rotating platforms for heavy-duty vehicles. They enable safe and smooth rotation in these specialized systems.
  • Medical and Rehabilitation Equipment: Slewing rings are used in medical and rehabilitation equipment, such as patient lifts and adjustable beds. They allow for smooth and controlled movement, aiding in patient care and mobility assistance.

In summary, a slewing ring is a specialized bearing that enables controlled rotational movement between components in mechanical systems. Its ability to support various loads, provide smooth rotation, and accommodate different applications makes it a valuable component in a wide range of industries.

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 different types and configurations of slewing rings available in the market?

Slewing rings are available in various types and configurations to cater to the diverse needs of different applications. The following are the different types and configurations of slewing rings commonly available in the market:

  • Single-Row Ball Slewing Rings: This type of slewing ring consists of a single row of balls placed between two rings. It offers compact design, low weight, and high load-carrying capacity. Single-row ball slewing rings are commonly used in applications where axial and radial loads need to be supported.
  • Double-Row Ball Slewing Rings: Double-row ball slewing rings have two rows of balls, providing higher load-carrying capacity compared to single-row designs. They are suitable for applications that require increased load capacity and improved stiffness.
  • Three-Row Roller Slewing Rings: Three-row roller slewing rings feature three rows of rollers arranged in a crisscross pattern. This configuration allows for higher load-carrying capacity and increased rigidity. Three-row roller slewing rings are commonly used in heavy-duty applications where significant radial, axial, and moment loads need to be supported.
  • Ball and Roller Combination Slewing Rings: In some cases, slewing rings are designed with a combination of ball and roller elements. This configuration provides a balance between load capacity and reduced friction. It offers improved rotational characteristics and is often used in applications requiring high load capacity and smooth rotation.
  • Internal Gear and External Gear Slewing Rings: Slewing rings can be equipped with internal or external gears. Internal gear slewing rings have the gear teeth on the inner ring, while external gear slewing rings have the gear teeth on the outer ring. The gear mechanism allows for controlled rotation and can be driven by external components such as motors or hydraulic systems. The choice between internal or external gear configuration depends on the specific application requirements.
  • Non-Gear Slewing Rings: Some slewing rings are designed without integrated gears. These non-gear slewing rings are often used in applications where the rotation is driven by external components or when a separate gear mechanism is already in place.
  • Customized and Specialized Slewing Rings: In addition to the standard types and configurations, slewing rings can be customized and designed to meet specific application requirements. Customized slewing rings may involve variations in dimensions, load capacity, gear specifications, sealing systems, or materials to suit unique applications or challenging operating conditions.

The availability of different types and configurations of slewing rings allows for the selection of the most suitable design based on factors such as load requirements, space limitations, rotational speed, environmental conditions, and application-specific needs. It is essential to consider these factors when choosing a slewing ring to ensure optimal performance and reliability in the intended application.

3.  The installation datum plane and bracket installing plane should be clean, grease, burr, paint and other foreign body should be wiped off.

Installation:

1. The screws in the installing plane should be fit with the mounting holes in the slewing bearing
2.  The slewing bearing has a soft zone marked with an “s” on the upper surface, when installing the bearing, it is important to ensure that this area is placed in a non-load or infrequent load zone.
3.  When the bearing is placed on the supporting frame work it is important to check the interface between these 2 surfaces. This check should be carried out with the insertion of feel gauges between the 2 surfaces. If a gap should exist then it is recommended to plane/resurface the effective area so as to remove the gap.
4.  Install slewing bearing with high strength screws, and choose appropriate strength bolts. All bolts are required to be tightened evenly. The sequence of this tightening process is shown in Pic. Welding of bearing is not allowed, in the event of welding any adjacent parts, heat transfer shall be avoided so as to cause the bearing to become deformed or change the hardness.
5.  After installation, the bearing should be rotated to check for smooth operation and any emission of unusual noise. If either of the aforementioned are noted, then the bearing should be adjusted to eliminate them. The teeth of the largest run-out are coated with green paint.
