The RSM Series are fully bonded, restrained elastomeric isolators offered in three designs - the RSM1 through RSM3 in load ranges up to 20,000 lbs. The RSM Series isolators incorporate high quality elastomer bonded within a heavy-duty, ductile iron or welded steel housing for long life and durability. RSM Series is encapsulated in a welded steel housing with a minimum 1.0g seismic restraint capability. These isolators are excellent for use under HVAC, power generation and electrical equipment providing exceptional vibration isolation and seismic restraint.
