Crankshaft for Komatsu

The crankshaft 6162331202 acts as the primary rotating shaft within the engine block of Komatsu heavy machinery. It converts the linear reciprocating motion of the pistons into continuous rotational motion, which is then transmitted to the transmission and drivetrain to power the machine. This component features precision-machined connecting rod journals and main bearing journals, which facilitate the connection to the pistons and allow the shaft to rotate within the engine block. It also incorporates integrated counterweights designed to balance the inertial forces generated during the combustion cycle.

This component is compatible with various Komatsu engines used in equipment such as excavators, wheel loaders, bulldozers, motor graders, and industrial cranes. Proper lubrication of the bearing surfaces is necessary to maintain the rotational integrity of the shaft. The crankshaft serves as the backbone of the engine's internal power conversion system, ensuring that rotational energy is effectively transferred to the machine's propulsion and hydraulic systems.
