Product description：

The spherical roller thrust bearings incorporate a large number of asymmetrical rollers and have specially 

designed raceways with an optimum conformtiy.

   

The bearings can support very heavy axial loads and permit high speed operations.

This type bearings are suitable to accommodate radial loads in additiona to simultaneously acting axial 

loads.

Another important characteristic of spherical roller thrust bearings is their self-aligning capability. This 

makes the bearings insensitive to shafe deflection and misalignment of the shaft relative to the housing.

The spherical rollers guided by a pressed steel window-type or machined brass or steel cage, with the 

housing washer, form a non-separable unit.

Product features：

Axially symmetric races to support radial loads while maintaining high speeds and rotational accuracy

Tapered bore compensates for flexing shafts and fits to tapered shafts

CN (normal) radial internal clearance for applications that do not involve thermal expansion or atypical precision

Steel cage evenly spaces the rollers for even load distribution and prevents contact to reduce friction, vibrations, and noise

Three lubrication holes in the outer ring for lubrication in place
