STC is a vibration, shock and noise isolator which has been designed for the secure support of equipment installed in any direction.
Especially suitable for rugged applications, these isolators are used for the cabins and engines of off-road and agricultural vehicles, for motors, power packs and electrical equipment etc.
Manufactured as a one piece cylindrical Natural Rubber NR moulding for maximum resilience and isolation performance, the STC has a centrally bonded thick wall steel tube
Generally the top steel washer, lower rebound steel washer and equipment fixing screw are not supplied by Farrat, except against special orders.
Installation is very simple. The STC is fitted to a supporting frame or chassis by inserting it into a hole having rounded edges and a smooth bore. The fixing screw is passed through the equipment foot and top washer, through the steel tube and then tightened onto the lower washer with a nut.
Farrat reserve the right to alter a specification if it is in the interest of product improvement.
