Wärtsilä 8R22 crankshaft

The Wärtsilä 8R22 crankshaft is a heavy-duty forged steel component designed to convert the reciprocating motion of pistons into smooth rotational motion in medium-speed marine diesel engines. It is built to withstand high cyclic loads, bending forces, and torsional stresses during continuous operation. The crankshaft is precision-machined and dynamically balanced, with internal oil passages to ensure effective lubrication and long service life.
