The RLES RRS Series Jaw Coupling is a high-performance flexible coupling designed to provide reliable torque transmission with enhanced shaft mounting flexibility and ease of installation. It is specifically engineered for applications where secure fitment, extended shaft distance and consistent performance are essential.
The RRS Series combines the proven jaw coupling principle with optimized hub configurations, offering improved assembly convenience and dependable shaft connection. Its elastomeric spider element ensures effective shock absorption, vibration damping, and misalignment compensation.
Specially engineered hub configuration ensures secure shaft mounting with improved ease of installation and removal.
The elastomeric spider prevents direct hub contact, reducing wear, noise, and extending operational life.
Accommodates angular and parallel misalignment, minimizing stress on connected equipment.
No lubrication required, ensuring cost-effective and hassle-free performance.
Reduces torsional vibrations and absorbs impact loads, protecting machinery.
Simplified design allows quick installation and easy spider replacement, reducing downtime.
Components:
Metallic Hubs (RRS Type)
Precision-engineered hubs designed for secure shaft fitment and ease of handling. Manufactured from high-quality cast iron or Aluminium.
Elastomeric Spider (Flex Element)
Available in multiple materials:
• NBR (Buna-N) – High flexibility and damping
• Polyurethane – Higher torque and wear resistance
• Hytrel® – Suitable for high temperature and high torque applications
Working Principle:
Torque is transmitted through the compression of the elastomeric spider between the jaws of the two hubs. The RRS hub design ensures a firm and reliable shaft connection, while the elastomer absorbs shocks and accommodates misalignment for smooth operation.
