Product Introduction

The crankshaft is a critical rotating component in an internal combustion engine, responsible for converting the linear motion of pistons into rotational motion to drive the vehicle or machinery. Made from high-strength forged steel or cast iron, crankshafts are engineered to endure high torsional loads, vibration, and extreme temperatures. Ideal for heavy-duty trucks, construction equipment, marine engines, and industrial generators.
