The connecting rod bearing, code P50604-04, is an essential load-bearing component in the MAN L21/31 engine, enabling smooth rotation between the connecting rod and the crankshaft. Engineered to handle high dynamic loads and continuous lubrication, this precision bearing minimizes friction and absorbs operating stresses during each combustion cycle. Its accurate fit and advanced bearing materials protect critical rotating components, contributing to stable engine operation, reduced wear, and long-term durability under heavy-duty operating conditions.
