Spherical Thrust roller bearing

Spherical Roller Thrust Bearings

Spherical roller thrust bearings also called spherical thrust roller bearings have specially designed raceways and barrel-shaped rollers (convex rollers). The raceway of housing washer of this bearing type is spherical with the center of the radius located on the bearing axis. Spherical roller thrust bearings are separable design, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly, as well as maintenance inspections. The design provides self- alignment capability to the bearing, some shaft misalignment can be tolerated. The contact angle is approximately 45° enabling the bearing to support high axial load and radial load up to 55% of axial load. They are suitable for relatively high speeds. The bearings have pressed steel cages or machined brass cages. Because of the large load capacity and self-aligning characteristics, Spherical roller thrust bearing is often used for injection molding machines, crane hooks and other large machines.
