Enclosed Metal Isolators

For medium-heavy to heavy devices, up to 1650 kg per damper, we can offer our SA-range which encompasses five completely enclosed metal spring mount types with variants for each type.

The isolators consist of a machine made bottom cup spot welded to a base plate, pre-punched for holding down bolts, and, fitted into the cup, steel helical springs mounted on a neoprene high frequency vibration isolation pad. The springs would be held at the top by a pressure plate levelled by a set-screw operating through a tapped insert in the machine made top cup. The top cup would be jig formed to its base to enclose a neoprene snubbing ring to ensure lateral stability.
