Tapered Roller Bearing

Tapered Roller Bearing

The tapered bearings are held together typically by a an inner race that has a tapered surface for the bearings to roll against, and a flat inner radial surface to slide over a shaft. The outer race is the opposite, with the inner surface being tapered, and the outer surface being flat.

For higher thrust-load capacity, a 30-degree contact angle is used. 5. Tapered bearings are mounted pairs since they handle radial loads better than a single row of tapered bearings. For heavy-duty applications, two or four rows of tapered rollers are combined in a single unit in large bearings.
