Tapered Roller Bearings consist of four basic components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements), and the cage (roller retainer). The cone has a shoulder called the cone rib, which makes contact with the end of the roller to ensure alignment and resist axial loads. Due to the tapered races, the bearing will handle any combination of radial and thrust loads. Proper use of Tapered Roller Bearings requires two opposed bearings, where each applies a thrust load toward the other. The internal clearance in the bearing is controlled by adjustment during installation.
