The RRL Series Jaw Coupling is a robust and versatile flexible coupling designed to deliver reliable torque transmission with enhanced shaft connection options. It is widely used in industrial applications where secure shaft locking, ease of installation, and dependable performance are critical.
The elastomeric spider eliminates direct hub interaction, reducing wear, noise, and extending service life.
Accommodates angular and parallel misalignment, reducing stress on shafts, bearings, and connected equipment.
No lubrication required, resulting in lower operating and maintenance costs.
Absorbs dynamic loads and reduces torsional vibrations, improving system stability and equipment life.
Special hub design enables quick mounting and dismantling, minimizing downtime during maintenance.
Designed for space-efficient installations while delivering consistent and durable performance.
Components:
Specialized Metallic Hubs (RRL Type)
Manufactured from high-quality cast iron for maximum durability and strength.
Elastomeric Spider (Flex Element)
• NBR (Buna-N) – General purpose with excellent damping and shock absorption.
Working Principle:
Torque is transmitted through the compression of the elastomeric spider between the jaws of the two hubs. The specialized hub design ensures a firm shaft connection, while the flexible element absorbs shocks and accommodates misalignment for smooth power transmission.
Advantages
• Reduced risk of fretting and shaft damage
• Easy installation without complex tools
• High reliability in continuous industrial operation
• Interchangeable with standard jaw coupling profiles (where applicable)
Typical Applications
RRL Series Jaw Couplings are widely used in:
• Electric motor and gearbox connections
• Pumps and compressors
