Revision as of 00:28, 10 December 2010 by Addicted2speed (talk | contribs)
A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can handle. Two types: roller ball and metal collar cap type.
