Tapered Roller Bearings

Taper Roller Bearing consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

The taper roller bearing has the ability to carry combinations of large radial and thrust loads or to carry thrust load only. Because of the difference between the inner and outer raceway contact angles, there is a force component, which drives the tapered rollers against the guide flange
