What Are Seismic Snubbers?

Seismic snubbers are mechanical devices designed to reduce the impact of seismic forces on structures and equipment. They play a crucial role in protecting buildings, bridges, pipelines, and other critical infrastructure from damage during earthquakes or other seismic events. The primary function of seismic snubbers is to dissipate the energy generated by ground motion and prevent excessive movement or vibration in a structure.

VMC Group SR Series

The SR Series are passive seismic restraints designed to restrain mechanical equipment during a seismic event. Our snubber design incorporates thick elastomeric bearing surfaces designed to decelerate the seismic force input to the equipment while also restraining the equipment to the building structure. Designed to work in conjunction with either spring or elastomeric vibration isolators, The SR Series maintains a 1/4″ air gap in all directions between the steel housing and the elastomeric element in order to avoid short-circuiting of the isolator. The steel base and top plates incorporate two properly spaced and sized anchor bolt holes. The housing can also be welded to the mechanical equipment and supporting structure if required. These snubbers provide a minimum of 1.0g restraint capability in all directions.
