Thrust Bearings to Reduce Friction and Support Axial Loads

A thrust bearing, a type of rotary bearing, rotates between parts reducing friction and is designed to support an axial load (mostly in low-speed appliions). It is the axial bearing that permits rotation between parts. As a global leader in the bearing industry, BMC provides custom solutions to lead your industry.
