This product is a diesel engine-specific connecting rod bearing (rod bearing), suitable for Cummins, Shanghai Diesel Engine (Shangchai), Weichai and other brand engines. The connecting rod bearing is an important component of the engine crank connecting rod mechanism, installed between the big end of the connecting rod and the crankshaft connecting rod journal, bearing the huge impact force and friction generated by piston movement. It adopts high-quality wear-resistant alloy materials (copper-lead alloy / aluminum-tin alloy) and high-precision machining processes to ensure precise dimensions, good wear resistance and high fatigue strength. It is an ideal replacement part for engine overhaul and bearing replacement.
