D49 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.

  Bearings are constructed from a number of different materials and are made up from a steel backing and internal layers of metal and finished with an overlay. Bi-Metal bearings generally have an aluminium alloy that is bonded to the steel backing.
