Crankshaft

A crankshaft is a mechanical component that converts reciprocating linear motion into rotary motion, or vice versa. It consists of a crankshaft arm, crank pin, and main bearing journals, with this Hengji product specified in Sint D11. Precision crankshaft machining supports proper balance and crankshaft alignment. Common applications include engine crankshafts, pedal mechanisms, piston-driven pumps, and manual winches. The crankshaft's geometry determines stroke length and torque output. Heat-treated surfaces provide wear resistance at bearing interfaces. Reliable and robust, the crankshaft is one of the automotive components used for power transmission in internal combustion engines and reciprocating machinery.
