SIT TRASCO Elastic Couplings
SIT TRASCO are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a polyurethane element. They transmit torque through pressure-stressed elastic star-shaped buffer which absorbs shock and torsional vibration. This element is oil, chemicals and heat resistant and electrically conductive. The elastic elements are available in different colors according to their hardness. Hubs are made of steel, cast iron or aluminium alloy in various versions as unbored, with finished H7 bore, with Taper Lock bore or with flange.
TRASCO couplings can be used for both directions of rotation and each mounting position.

Typical Applications
SIT TRASCO elastic couplings are intended for the highest performance in a wide range of industries.
They are particularly applied in compressors, pumps, conveyors and construction machinery. From small precision instruments to heavy duty conveyor drives and packaging machines in the food, chemical, glass, paper, wood and rubber industries.
Properties
