Product Description

Crossed roller bearings, also known as crossed roller slewing bearings or crossed roller slide bearings, are a specialized type of rolling element bearing. They are designed to handle both radial and axial loads while providing high rotational accuracy and stiffness.

Crossed roller bearings often require preload to optimize their performance. Preload refers to the internal axial force applied to the bearing to eliminate clearance and ensure proper contact between the rolling elements and raceways. Preloading enhances the bearing's stiffness, reduces deflection, and improves its ability to handle axial and radial loads. However, excessive preload can lead to increased friction and heat generation. The appropriate preload level depends on factors such as the application's load requirements, rigidity needs, and operating conditions.

Crossed roller bearings can be equipped with various sealing options to protect against contaminants and retain lubrication. Common sealing methods include contact seals, non-contact seals (such as shields or labyrinth seals), or a combination of both. Seals help extend the bearing's service life by minimizing the entry of dust, dirt, moisture, and other harmful particles. The choice of sealing option depends on factors such as the application environment, speed, and the level of protection required.
