Bearing (plain bearings)

Plain bearings are generally used for the crankshaft, cam ring, camshaft, connecting rods, and the accessory drive shaft bearings. Such bearings are usually subjected to radial loads only, although some have been designed to take thrust loads. They are usually made of nonferrous (having no iron) metals, such as silver, bronze, aluminum, and various alloys of copper, tin or lead. (See also bushings).
