Crankshafts are widely applied in various internal combustion engines and power machinery, including:
Automotive Engines
Marine Diesel Engines
Construction Machinery (Excavators, Bulldozers, Road Rollers)
Agricultural Machinery (Tractors, Harvesters)
Power Generation Equipment (Diesel & Gas Generators)
In real-world applications, crankshafts bear high cyclic loads and friction forces, directly determining engine reliability and service life. Whether in high-speed automotive engines or heavy-duty marine diesel engines, high-performance crankshafts ensure stable operation and efficient power output.
Q1: What manufacturing processes are used for your crankshafts?
A1: Our crankshafts are primarily produced using forging and casting processes, with the method chosen according to customer requirements.
Q2: Can you produce crankshafts according to customer drawings?
A2: Yes, we offer OEM/ODM services and can manufacture based on drawings or samples.
Q3: What surface treatments are available for crankshafts?
A3: Common surface treatments include nitriding, induction hardening, and shot peening to enhance wear resistance and fatigue strength.
