The connecting rod, code P50603-02, is one of the most vital components in the MAN L21/31 engine, serving as the mechanical link between the piston and the crankshaft. Engineered to withstand extreme tensile and compressive forces, this forged steel rod converts the reciprocating motion of the piston into rotational movement, delivering efficient power transmission. Its precision-machined bearing surfaces and optimal weight balance are critical to minimizing vibration and maintaining high mechanical integrity during continuous operation in marine and stationary power generation environments.
