GR-24 Series Complete Coupling

The GR-24 Series is a robust, torsionally flexible industrial coupling designed for reliable power transmission and shock absorption. This complete set features two high-strength hubs and a precision-moulded polyurethane spider, engineered to protect connected machinery by dampening torsional vibrations and compensating for shaft misalignments.

Superior Torque Handling: Rated for 60Nm (with Red 98 Sh-A insert), providing high torque density in a compact frame—perfect for electric motor drives, centrifugal pumps, and fans.
98 Shore A Hardness Insert: The high-durometer red polyurethane spider offers excellent resistance to oils, chemicals, and extreme temperatures (-30°C to +90°C continuous / up to 120°C peak).
Vibration Damping: The curved jaw design is specifically optimized to absorb operational shocks and resonance, significantly extending the service life of bearings and seals.
Durable Hub Construction: Available in high-quality sintered steel or cast iron, providing the structural mass needed for steady-state industrial power transmission.
Fail-Safe Operation: Designed as a “fail-safe” coupling; the jaws will remain interlocked to transmit torque even if the elastomer spider is completely destroyed in an overload event.
