Crankshaft
The crankshaft is a crucial component in an internal combustion engine, transforming linear piston movement into rotational energy necessary for powering the vehicle. Crafted from high-strength materials to withstand extreme temperatures and pressure, this precision-engineered part ensures smooth operation and optimal performance. Its design features key elements such as journals, counterweights, and a unique shape that help maintain balance and reduce vibrations during engine operation. Whether for high-performance racing engines or standard vehicles, the crankshaft plays an essential role in enhancing efficiency and durability, making it vital for anyone looking to maintain or upgrade their engine system.

Cummins NT855 crankshaft is a core transmission component engineered for NT855 series heavy-duty diesel engines, compatible with Shantui TY230 bulldozers, Yishan TY200 bulldozers, mining dump trucks and various stationary generator sets. As the central power-output shaft of the engine, it is integrally forged from high-strength alloy steel, followed by quenching and tempering treatment plus induction hardening on journal surfaces to reach a hardness of HRC55–60. It boasts outstanding fatigue resistance and wear resistance, capable of enduring bending and torsional stress generated during long-term high-load operation (torque range: 1420–1790 N·m), serving as an essential foundational part to sustain continuous and efficient equipment performance.
With 20 years of extensive experience in the sales and maintenance of Cummins engines and parts, we provide robust power solutions ranging from 175HP to 2500HP. Our core product lineup includes the NTA855, KTA19, KTA38, KTA50, QSK60, and M11 series.
