The complex requirements and the increasingly higher loads that the crankshaft crescents of the moving parts of the engine, such as the crankshaft, connecting rods, drives and camshafts, have to support, require the use of adaptable materials to these conditions and high temperatures.

To offer total reliability, the NPC ® Crankshaft Crescents are made of steel and coated with other antifriction metals such as aluminum, tin and copper as additives.
