Applications:sicus cup spring isolators are recommended for use in isolating sources of noise and vibration locatednear critically quiet areas. They are highly effective for control of both high and low frequency vibrationproduced by reciprocating refrigeration compressors, pumps, packaged air-handling and airconditioningequipment, centrifugal and axial fans, inertia bases, internal bases, internal combustionengines etc. Features:- laterally stable springs with neoprene tap and base.- colour coded springs according to load ratings.- non-skid bolt down base.- plated leveling lock bolt.- isolates low frequency vibration.- springs are designed for 50% overload capacity.
