Spherical-Roller Bearings Two rows of rollers give these bearings load capacities over five times higher than comparably sized tapered-roller bearings.

The thrust roller bearings, roller, and cage assemblies rest between the raceway rings. Spherical?thrust roller bearings rely on convex rollers and have a self-aligning capability because of the barrel-shape of
the rollers. The bearings consist of one row of rollers and have a larger contact angle.
