Thrust tapered roller bearing, single-row, imperial, 76.454 x 133.350 x 33.338 mm, Timken.

Single-row thrust tapered roller bearing consist of two thrust races, a set of rollers and a cage. This design can create up to 40 percent more capacity than cylindrical and spherical bearings with the same envelope dimensions. This configuration creates a benefit called true rolling motion. The extensions of the raceways and rollers converge at a common point (the apex) on the axis of rotation. As a result, true rolling motion reduces heat generation and wear on the races and rollers.
