    Ruland jaw couplings have a curved jaw profile that press fits with the spider for consistent zero-backlash performance. The balanced hub design allows for reduced vibration at high speeds. Full range of inch/metric clamp-style and set screw hubs with or without keyways. Coupling hubs are machined from high grade (type 2024 t351) aluminum bar stock for precise fit, superior strength, and bright finish. The advanced polyurethane material of the spider dampens impulse loads while minimizing shock to the motor, bearings and other sensitive equipment. Spider comes in three different materials including 85 Shore A - Blue for greatest dampening, 92 Shore A - Yellow for accuracy with a small amount of dampening, and 98 Shore A - Red for torsional stiffness and highest torque. Jaw couplings are considered fail safe because if the spider fails the jaws of the two hubs interlock for direct power transmission allowing the machine to be shut down safely. The coupling is designed with the spider as the wear element making replacement cost effective and simple. Replacing the spider will restore the capabilities of the coupling. Hardware is metric and exceeds industry standards for maximum torque capabilities. Manufactured by Ruland in our Marlborough, MA factor under strict controls using proprietary processes.
