Tapered Roller Bearings are designed to take Radial and Thrust loads from one direction. ​They consist of the inner race (cone) with cage guided rollers and the outer race (cup). The track has the same profile as the tapered rollers. The extension of the contact lines meet at the common point on the bearing axis of rotation. The cone and cup are separable. By using two bearings as opposed mountings they can carry thrust loadings in both directions.

Single Row Tapered Roller Bearings can be supplied matched in DB or DF arrangement. These matched bearings are manufactured so that the pair should have an established initial axial clearance when they are mounted opposite to each other. They should also have a uniform distribution of the loading. Matched bearings are used when the load carrying capacity of a single bearing is not sufficient. They are also used when thrust loads have to be carried at a certain axial clearance in both directions.

The axial clearance of single Tapered Roller Bearings is adjusted on assembly.
