Slewing ring bearings are large-size rolling bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction .They can perform both slewing (oscillating) movements as well as rotational movements. A slewing ring bearing consist of an inner ring, an outer ring and rolling elements (balls or cylindrical rollers) that are separated by polyamide spacers .The rings, 1 of which usually incorporates a gear ,are provided with holes to accommodate attachment bolts. The holes may be threaded. Generally , only the raceways in the rings are hardened and precision-ground.Integral seals made of acrylonitrile-butadiene rubber (NBR) keep the lubricant in, and contaminants out of the bearing. Slewing ring bearings are re-lubricated through grease fittings to reduce maintenance and operating costs.

Compared to traditional pivot arrangements, slewing ring bearing arrangements provide many design and performance advantages. The compactness and large inner diameter simplify the design of the bearing arrangement and its associated components .The low sectional height of these bearings means that the pinion lever can be kept short. In most cases only flat mounting surfaces on the associated components are needed.

Slewing ring bearings were originally designed to be mounted only on horizontal support structure, but can now be used successfully in vertical bearing arrangements .

Slewing ring bearings perform extremely well in a variety of applications such as:
¤ Access platforms
¤ Bucket wheel excavators
¤ Conveyor booms
¤ Cranes of all type
¤ Small ,medium and large excavators
¤ InHangZhou tables
¤ Ladle turrets
¤ Offshore applications
¤ Robots
¤ Railway bogies
¤ Rotary platforms
¤ Stackers
¤ Solar mirrors
¤ Tunnel boring machines
¤ Wind turbines

What role do seals and shields play in protecting cross roller bearings from contaminants?

Seals and shields play a crucial role in protecting cross roller bearings from contaminants. These protective devices are designed to prevent the entry of foreign particles, such as dust, dirt, moisture, and other contaminants, into the bearing system. They offer several functions that contribute to the overall protection and longevity of cross roller bearings:

  • Contamination Prevention:
  • The primary role of seals and shields is to prevent contaminants from entering the bearing. They create a physical barrier that blocks the passage of particles into the internal components of the bearing. This is particularly important in industrial environments where cross roller bearings are exposed to various contaminants that can cause damage and premature wear. By effectively sealing the bearing, seals and shields help maintain a clean and controlled operating environment, ensuring the reliable and optimal performance of the bearing.

  • Retention of Lubrication:
  • Seals and shields help retain the lubricant within the bearing, preventing its leakage and ensuring proper lubrication of the internal components. Lubrication is essential for reducing friction, minimizing wear, and dissipating heat within the bearing. The presence of seals or shields helps to retain the lubricating grease or oil, preventing its loss due to evaporation or contamination. This ensures that the cross roller bearing remains properly lubricated, promoting smooth operation and extending the service life of the bearing.

  • Protection against Moisture:
  • Moisture can be a significant source of contamination and can lead to corrosion and damage to the bearing components. Seals and shields act as a barrier against moisture ingress, preventing water or other liquids from reaching the internal parts of the bearing. By protecting against moisture, seals and shields help maintain the integrity of the bearing, reducing the risk of corrosion and preserving its performance and longevity.

  • Reduction of Friction and Wear:
  • Seals and shields also contribute to reducing friction and wear within the cross roller bearing. They provide an additional layer of protection and help minimize the contact between the rolling elements and the raceways. This reduces the frictional forces and wear on the bearing components, increasing their lifespan and improving overall efficiency. By reducing friction and wear, seals and shields help maintain the precision and performance of the cross roller bearing, ensuring smooth operation and minimizing energy losses.

  • Prevention of Lubricant Contamination:
  • Seals and shields play a vital role in preventing the contamination of the lubricant itself. They act as a barrier against external contaminants, such as dust and dirt, which can mix with the lubricant and degrade its quality. Contaminated lubricant can lead to increased friction, accelerated wear, and decreased performance of the cross roller bearing. The presence of seals and shields helps to maintain the cleanliness and integrity of the lubricant, ensuring its effectiveness in reducing friction and providing proper lubrication to the bearing components.

In summary, seals and shields play a critical role in protecting cross roller bearings from contaminants. They prevent the entry of foreign particles, retain lubrication, protect against moisture, reduce friction and wear, and prevent lubricant contamination.

The rollers are oriented at right angles to each other and are alternately crossed, forming an X-shaped pattern. This arrangement allows for efficient load distribution, enabling cross roller bearings to support both radial and axial loads simultaneously. The crossed roller design enhances the load-carrying capacity while maintaining a compact profile.

  • Structure of Rings:
  • The rings of cross roller bearings have a specific structure to accommodate the arrangement of rollers. The inner and outer rings are typically thin-walled, which helps reduce weight and improve the flexibility of the bearing. The thin-walled structure also contributes to the compactness of cross roller bearings, making them suitable for applications with limited space. The rings are precision-machined to ensure accuracy and rigidity, providing a stable foundation for the rollers.

  • Preload Mechanism:
  • Cross roller bearings incorporate a preload mechanism to enhance rigidity and minimize clearance. Preloading refers to applying a controlled axial force on the bearing components to eliminate any internal clearance. This axial force is achieved through various methods, such as using spacers, adjusting the ring thickness, or applying a preloading spring. The preload mechanism ensures that the rollers are in constant contact with the raceways, reducing backlash and improving the bearing's precision and rigidity.

  • Functions of Cross Roller Bearings:
