The RJB Series Jaw Coupling is a robust and flexible coupling designed for efficient torque transmission with high reliability. It is ideal for industrial applications requiring Backlash-Free, secure shaft connection, vibration damping, and ease of maintenance.
The RJB Series combines the proven jaw coupling principle with precision-engineered hubs and an elastomeric spider element, ensuring shock absorption, misalignment accommodation, and long service life. This makes it suitable for a wide range of medium to heavy-duty industrial machinery.
Provides reliable torque transmission while remaining space-efficient for industrial installations.
Hubs and elastomeric elements are designed for quick assembly and disassembly, reducing downtime.
The elastomeric spider absorbs shocks and torsional vibrations, protecting connected equipment and extending lifespan.
Accommodates angular and parallel misalignment to reduce stress on shafts, bearings, and motors.
Prevents hub-to-hub wear, minimizing maintenance and operational noise.
No lubrication is required, ensuring clean and cost-effective operation.
Ensures consistent torque transmission across a wide range of industrial applications.
Components:
Metallic Hubs (RJB Type)
High-quality cast iron or steel hubs engineered for secure shaft mounting and robust torque handling.
Elastomeric Spider (Flex Element)
Available in multiple materials:
• 92 ShA: General-purpose applications with high damping
• 98 ShA: Higher torque capacity and wear resistance
• 64 SH D: Suitable for high temperature and high torque conditions
Working Principle:
Torque is transmitted through the compression of the elastomeric spider between the jaws of the hubs. The flexible element absorbs shocks and accommodates misalignment, providing smooth and reliable operation. The RJB hub design ensures secure shaft fitment and high torque capability.
