Resilient Coupling - Z & Y Series Manufacturer in Ahmedabad, India
Resilient Coupling - Z & Y Series from Super Mech Industries is made in Ahmedabad, India in 18 catalogue sizes, RC 1 to RC 23, with bores finished to order up to 173 mm.
Resilient Couplings in the Z & Y Series use spring and rubber components arranged in a manner that provides high torsional flexibility. These couplings are specially designed to absorb shocks and vibrations during start-up and operation, reduce transmission noise, and accommodate limited shaft misalignments. They are widely used in machinery where frequent starting, reversing, or shock loads are encountered. Their rugged design and efficient damping capabilities make them ideal for harsh industrial conditions.
