GR-42 Series Complete Coupling
The GR-42 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 450Nm (with Red 98 Sh-A insert), providing the rugged capacity required for heavy-duty industrial drives, large fans, and screw compressors.
-
98 Shore A Hardness Insert: The high-durometer red polyurethane spider provides 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 optimised to absorb operational shocks and resonance, significantly extending the service life of bearings and seals in high-torque drive-trains.
-
Durable Hub Construction: Supplied in high-quality cast iron (GJL) or steel, providing the structural mass and durability required 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 fails, preventing a complete loss of drive in critical systems.
