Bearings • Thrust Bearings

Thrust bearings are rotary bearings that allow rotation between parts and support a high axial load at moderate speeds. Design varieties include ball thrust bearings, tapered roller bearings, fluid bearings and magnetic bearings. Due to their inability to support radial loads, thrust bearings must be paired with radial bearings for radial load support. They are offered as flat race thrust bearings, one directional, grooved race thrust bearings and two directional, grooved race thrust bearings.
