MAN – 7L27/38 – CRANKSHAFT

The MAN 7L27/38 crankshaft is a high-strength marine 7-cylinder medium-speed diesel engine crankshaft assembly engineered for heavy-duty power transmission in propulsion plants and auxiliary marine generator sets across commercial vessels, cargo ships, and offshore platforms. Built to world-class maritime classification standards, this heavy-forged industrial marine diesel crankshaft unit features precision-ground main bearing journals, crankpins, and balanced counterweights designed to convert reciprocating piston power under extreme peak firing pressures, heavy torque loads, and continuous torsional vibration. Ideal for main engine overhauls, routine power plant maintenance, and emergency crankshaft replacements, the MAN B&W 7L27/38 marine crankshaft delivers superior mechanical fatigue resistance, operational reliability, minimized downtime, and long-term continuous-duty engine performance across critical maritime power infrastructures.
