Jaw Couplings

The Jaw Coupling is a versatile elastomeric coupling designed to transmit torque while compensating for axial, radial, and angular shaft misalignments. At the heart of the Jaw Coupling is a flexible spider, typically made from polyurethane or NBR, which sits between the interlocking metal jaws of two hubs. This design effectively dampens torsional vibrations and absorbs shock loads, protecting bearings and extending the machinery's lifespan. The Jaw Coupling requires no lubrication and provides electrical insulation, preventing stray currents from damaging motor bearings. Manufactured from cast iron, aluminum, or steel, the hubs are available with standard bores or custom keyways. Because of its simple, robust construction and ease of maintenance, the Jaw Coupling is a highly reliable solution for pumps, gearboxes, and standard industrial drive trains.
