The H / HR Series Jaw Coupling is a heavy-duty flexible coupling designed for high torque transmission and demanding industrial applications. It is specifically engineered to handle higher power requirements, larger shaft sizes, and increased operational loads compared to standard jaw couplings.
The H / HR Series combines a rugged metallic hub design with a high-capacity elastomeric element, delivering superior performance in applications involving shock loads, vibration, and moderate misalignment. It is ideal for industries where strength, durability, and reliability are critical.
Designed to transmit significantly higher torque than standard jaw coupling series, suitable for heavy-duty applications.
Engineered with strong metallic hubs to withstand high loads and demanding operating conditions.
Elastomeric element eliminates direct hub interaction, reducing wear, noise, and maintenance.
Accommodates angular and parallel misalignment, protecting connected equipment from stress.
Absorbs dynamic loads and dampens torsional vibrations, ensuring smooth operation.
No lubrication required, reducing maintenance costs and operational complexity.
Built for durability with high resistance to wear and fatigue under continuous operation.
Components:
Heavy-Duty Metallic Hubs (H / HR Type)
Manufactured from high-strength S.G. Iron. Designed for large bore sizes and high torque transmission.
Elastomeric Spider (High-Capacity Element)
Available in:
• NBR (Buna-N): High damping for general applications
• Polyurethane: Enhanced torque and wear resistance
• Hytrel: High temperature and high torque capability
Working Principle:
Torque is transmitted through the compression of the elastomeric spider between the jaws of the hubs. The heavy-duty hub design ensures reliable torque transfer, while the elastomer absorbs shocks and accommodates misalignment for smooth and efficient operation.
