AROFLEX GR-65 Complete Coupling

GR-65 Series Complete Coupling

The GR-65 Series is a robust, torsionally flexible industrial coupling designed for high-power transmission and exceptional shock absorption. This complete set features two high-strength hubs and a precision-moulded polyurethane spider, engineered to protect heavy machinery by dampening torsional vibrations and compensating for significant shaft misalignments.

• Superior Torque Handling: Rated for 940Nm (with Red 98 Sh-A insert), providing the massive capacity required for heavy-duty conveyors, large-scale industrial mixers, and high-pressure pumping systems.

• 98 Shore A Hardness Insert: The high-durometer red polyurethane spider provides exceptional 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 in high-torque, high-mass drive-trains.

• Durable Hub Construction: Typically supplied in high-quality cast iron (GJL) or steel, providing the structural mass and durability required for steady-state heavy industrial power transmission.

• Fail-Safe Operation: Designed as a “fail-safe” coupling; the jaws remain interlocked to transmit torque even if the elastomer spider is destroyed, preventing complete system failure in critical industrial applications.
