The Wellman Taper Grid Resilient Coupling has unique shock absorbing and de-tuning properties. The Taper grid is made of specially rolled high tensile taper section alloy spring steel material with particular technical care in shape formation, followed by hardening and tempering by controlled process. The unique design of hub teeth profile facilitates the gentle insertion of the taper grid into the taper grooves on the hub periphery during installation and maintenance. Thus, it gives long life in transmitting progressive load under torsional shock condition.
