| High Light | Machined Forged Disc ，Hydraulic Drive Coupling Forgings ，carbon Steel Forgings OEM | ||
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.
Material Strength: Made from medium/high-carbon steel, optimized for load-bearing and shock absorption.
Precision Machining: CNC-finished to meet close dimensional tolerances and surface flatness.
Durability: High wear and fatigue resistance for extended service life under cyclic torsion.
Custom Configurations: Available in various sizes and keyway profiles based on customer specifications.
Hydraulic pump-to-motor shaft couplings
Power transfer assemblies in mobile hydraulic systems
Construction machinery, mining conveyors, and press equipment
Any high-torque system requiring stable and aligned rotational connection
