Crankshaft Bearings

Crankshaft bearings are critical engine components located within the crankcase, supporting the crankshaft and enabling smooth rotational movement. These bearings reduce friction between the crankshaft journals and the engine block, preventing metal-to-metal contact and ensuring efficient power transfer. Designed for passenger cars and commercial vehicles, crankshaft bearings are subjected to high loads and speeds, necessitating robust construction from materials like tri-metal or polymer-coated steel. Regular replacement is essential for maintaining engine performance and preventing catastrophic failure. Examples in our assortment include MAN crankshaft bearings (MPN 51.01113-6082) and a variety of MAHLE bearings such as MPN 227HS21013000 and 037AS21910000.
