Main Bearings
In a piston engine, the main bearings are the bearings which hold the crankshaft in place and allow it to rotate within the engine block.
Main bearings are usually plain bearings or journal bearings, held in place by the engine block and bearing caps. The number of main bearings per engine varies between engines, often in accordance with the forces produced by the operation of the engine.
