Customized Heavy Duty Forged Transmission Coupling

Forged Transmission Coupling

This heavy-duty forged steel coupling is integrally forged from high-strength alloy steel. After forging and heat treatment, the metal grain structure is compact and continuous. Its mechanical properties are far better than cast couplings, featuring high tensile strength, excellent impact resistance and fatigue resistance, designed for ultra-high torque heavy-load working conditions.

The coupling adopts split yoke structure with precise CNC machining for high dimensional accuracy. The surface is coated with anti-corrosion paint for rust and wear protection, suitable for harsh industrial environments. It can transmit huge torque steadily, absorb shock loads and reduce vibration of transmission system to ensure long-term stable operation of heavy machinery.

ETERNAL's Manufacturing Advantages

• Forged Body: The coupling is integrally forged, free of casting defects such as blowholes and sand inclusions. It features excellent tensile strength and toughness, and is resistant to impact and fracture.

• Heat Treatment Process: The coupling undergoes integral quenching and tempering to improve hardness and comprehensive mechanical properties for an extended service life.

• Precision Machining: The coupling is processed by CNC machining, delivering high fitting accuracy, good concentricity and smooth power transmission.

• Anti-corrosion Coating: Heavy-duty industrial paint is applied to the coupling for rust and oil resistance, suitable for harsh environments including workshops and open-air sites.

• Custom Non-standard Products: ETERNAL can customize bore diameters, overall dimensions and torque specifications according to customer drawings. It meets the power transmission requirements of heavy-load equipment such as metallurgical machinery, mining equipment, heavy machinery, rolling mills, large hoisting equipment, shield machines and raise borers.
