Product Description
This unique range of Open Spring mountings uses integral rubber end fixing of the springs which sets them apart from all other designs. Larger capacity open spring mountings use rubber grommets and base pads to ensure no direct metal path between the machine and the seating, thus enhancing high frequency noise isolation.
Originally designed for use with Type IPF Inertia Pouring Frames, the OS mountings are now widely used to isolate vibration from every conceivable type of rotating and reciprocating machine. Where control of transient motion is required Open Spring mountings can be used in conjunction with our Viscous Dampers Type SFD.
