Bearings

Bearings. A bearing is a component used to reduce friction and to maintain clearance between stationary and rotating components of the engine. Bearings, or bearing surfaces, are located on the crankshaft, connecting rod, and camshaft, and also in the cylinder block. Bearings can be subjected to radial, axial (thrust), or a combination of radial and axial loads.
