The RRJ Series Jaw Coupling is a compact and reliable flexible coupling designed for general-purpose industrial applications requiring easy installation and dependable shaft connection. It combines the proven jaw coupling principle with optimized hub design for quick assembly and secure fitment.
The RRJ Series is ideal for applications where simplicity, compactness, and cost-effectiveness are important, while still delivering efficient torque transmission, vibration damping, and misalignment accommodation.
Ideal for installations with limited space, without compromising performance.
Simplified hub design enables quick mounting and dismantling, reducing installation time.
Elastomeric spider prevents direct hub interaction, reducing wear, noise, and maintenance.
No lubrication required, ensuring clean and cost-effective operation.
Accommodates angular and parallel misalignment, protecting connected equipment.
Absorbs dynamic loads and reduces torsional vibrations for smooth system operation.
Provides consistent torque transmission across a wide range of operating conditions.
Construction & Working Principle
Components:
Metallic Hubs (RRJ Type)
Designed for easy installation and secure shaft fitment. Manufactured from high-quality S.G Iron or steel.
Elastomeric Spider (Flex Element)
Available in multiple materials:
• 92 ShA: General-purpose applications with high damping
• 98 ShA: Higher torque capacity and wear resistance
• 65 Sh D: Suitable for high temperature and high torque conditions
Working Principle:
Torque is transmitted through the compression of the elastomeric spider positioned between the jaws of the hubs. The flexible element absorbs shocks and accommodates misalignment, ensuring smooth and efficient power transmission.
