SIT TRASCO ES Elastic Elements
AESS elastic elements are parts designed for SIT TRASCO ES zero-backlash shaft couplings.
SIT TRASCO ES are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a polyurethane element. They transmit torque through a high-precision 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.
