Thrust Bearings

A thrust bearing is a type of rotary bearing. Similar to other rotary bearings they permit rotation between parts, but thrust bearings are designed to support a high axial load. Thrust bearings come in several varieties, most common being ball thrust bearings and tapered roller thrust bearings.

Ball thrust bearings utilize ball bearings supported in a ring, and are used in low thrust applications where there is little radial load.Tapered roller thrust bearings consist of small tapered rollers arranged so that their axes all converge at a point on the axis of the bearing. The length of the roller and the diameter of the wide and the narrow ends need to be carefully calculated to provide the correct taper so that each end of the roller rolls smoothly on the bearing face without skidding.

Roller thrust bearings are the type most commonly used in automotive applications where they are used in pairs to accommodate axial thrust in either direction, as well as radial loads. Roller thrust bearings can support larger thrust loads than the ball type due to the larger contact area, but are more expensive to manufacture.
