Tapered roller bearing - Wikipedia

A tapered roller bearing is a unit that consists of both tapered raceways (inner and outer rings), and tapered rollers. The construction is intended for coination loads, such as dual acting axial and radial loads. The bearing axis is where the projected lines of the raceway coine at a common loion to improve rolling, while reducing friction.
