Vibra Trol ® 174
OML*/OM Type -
Free Standing Spring Mount
Use: The economical OM Series Free Standing
Spring Mounts are utilized to isolate floor mounted
equipment where transmission of noise and
vibration (below 1200RPM) is apparent.
Note: Not recommended when subject to
wind loads and weight changes.
Features: Spring is welded to lower load plate and
upper compression plate. Mounting is facilitated by
an adjustable leveling bolt. Base plate is furnished
with a skid-resistant neoprene backing, making
anchoring optional. Allows up to 2.10" (53.3)
deflection (larger deflection mounts available).
Typical Applications: Refrigeration compressors,
packaged air handling and refrigeration equipment,
centrifugal fans, close coupled and base mounted
pumps and similar apparatus. May also be used as
a vibration dampening device for pipe risers.
Notes: To ensure minimum effective vibration control, the spring mount must have a static deflection at least three times (3X)
greater than the floor spans deflection.
Spring devices are stable with a vertical and horizontal spring constant equal to one (Kx/Ky=1). A 50% additional run-out from
rated capacity to solid load is also characteristic of spring type isolators.
