Plane Bearings

Plane Bearings are other wise known as plain bearings, sleeve bearings or bushings. These bearings do not have any rolling elements such as balls or rollers. Plane bearings can take more force than a roller or ball bearing.

Plane bearings can be integral, that is, the shaft sits directly on the groove. or as a form of bushing in which a semicylindrical sleeve is placed below the shaft. This has the advantage of being replaced when it worn. The sleeve is made of soft material as compared to the shaft.

Some plane bearings have two shells or sleeves. One above the shaft and one below. These bearings are used in the crankshaft of the engine.
