Machined Forged Disc Carbon Steel Coupling Forgings For Hydraulic Drive Assemblies

Our Machined Carbon Steel Coupling Forgings are engineered for precision fit and robust torque transmission in demanding hydraulic drive assemblies. Manufactured from high-quality medium to high carbon steel, these coupling components offer outstanding mechanical strength, machinability, and dimensional stability under fluctuating load conditions.

Through advanced open die forging techniques, each coupling blank achieves refined grain structure and directional fiber flow, ensuring superior fatigue resistance and structural integrity. Post-forging machining guarantees tight tolerances and surface finish required for seamless integration into rotating hydraulic systems.

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
