Acrefine Seismic Snubbers

All Directional Restraining

Acrefine AS-A and AS-AR type seismic snubbers are designed to limit in all directions equipment motion caused by external forces such as seismic events.

These snubbers are ideal for applications where all directional restraining is required. At least two snubbers must be installed opposite one another to limit movement of equipment when subject to seismic forces from any direction. Snubbers can also be utilized for vertical installations where there is no need to consider vertical forces.

AS-A and AS-AR type snubbers consist of two components. One is attached to the supporting structure and the other one to the equipment. Impact surfaces on the components are protected by elastic rubber. This reduces shock loads for improved performance during a seismic movement.


Key Features
  • All directional restraining
  • Load capacity up to 2400 kg (5290 lb) on standard range
  • Easily inspected for correct installation alignment
  • 7 mm (1/4″) thick replaceable rubber cushion on impact surfaces
  • Can be installed horizontally or vertically
  • E-Coated for superior corrosion protection
  • Can be bolted or welded in place

Acrefine AS-A and AS-AR type snubbers are designed for floor mounted equipment. They are suitable for applications where equipment is on resilient supports such as rubber or springs and thus all-directional restraining is required. When installed snubbers remain out of contact during normal operation. They are built to withstand seismic forces so that equipment can be held in place.

These snubbers come in different sizes and up to 2400 kg (5290 lb) load capacity. For higher load capacities or for special applications please contact us.
