Bearings are the most critical engine component. A plain bearing is fitted in the housing and slides with the shaft. It transmits load and motion simultaneously. Especially main and big end bearing shells are subject to high pulsating loads. The transfer of forces and high surface velocities, in addition to actual operating conditions, require simultaneous contradictory material features. Bearings typically consist of several layers; bi-metal bearings of bearing back and bearing alloy, three-metal bearings of bearing back with bearing alloy and overlay. Modern surface technologies includes electroplating, sputter and SYNTHEC®
