Bearings are mechanical assemblies that consist of rolling elements and usually inner and outer races which are used for rotating or linear shaft applications, and there are several different types of bearings, including ball and roller bearings, linear bearings, as well as mounted versions that may use either rolling element bearings or plain bearings. Ball bearings have spherical rolling elements and are used for lower load applications, while roller bearings use cylindrical rolling elements for heavier load carrying requirements.

Bearings are very important, as they crucially help to faciliatate motion betwene parts through reducing friction. Most, though, require regular maintenance to prevent failure and may need replacement if they fail.
