-
Seismic Zone 2 Capability: The housings
and anchor bolts are optimally designed for Seismic Zone 2 applications.
Minimum housing strength is 1.5 G's.
-
Superior Isolation Efficiency:
Series "920" Spring Isolators consist of ductile iron
casting housings and 1" deflection spring
elements. They provide excellent isolation of vibration over a wide frequency range.
-
Lateral Stability:
The free-standing
springs are laterally stable and designed to provide a 50% overload
capacity.
-
Vertical Limit Stops:
The adjustable
vertical limit stops control the vertical and lateral movements of isolated equipment that
are due to load changes and lateral seismic loads.
-
Ease of Installation:
A built-in
leveling bolt eliminates shimming in all applications and saves the cost of installation.
-
Effective Noise Reduction:
The resilient
washers interrupt structure-borne noise transmission paths. Noise amplifications caused by
sounding board effects are thus eliminated.
