Mounting Options
DIRECT MOUNT
No base required. Isolators are attached directly to equipment. Direct
isolation can be used if equipment is unitary and rigid without the use
of additional support. If there is any doubt whether or not equipment
can be supported directly on isolators, use rails or consult the factory.
Isolators
NEOPRENE MOUNTS
Neoprene mountings consist of a steel top plate and base plate completely
embedded in colored (oil-resistant) neoprene for easy identification
of capacity. Neoprene mountings are furnished with a tapped hole in
the center. This enables the equipment to be bolted securely to the
rubber mount.
RESTRAINED SPRING MOUNTS
Restrained spring isolators consist of laterally stable, free-standing springs
assembled into a steel housing. These assemblies are designed for vertical
and horizontal motion restraint. Restrained spring isolators can be used for
blocking during equipment installation and are provided with leveling bolts.
Springs provide 50% overload capacity and are color-coded or identified
to indicate load capacity. Restrained spring mounts are recommended for
equipment subject to wind loading or large torquing forces.
FREE-STANDING OPEN SPRING MOUNTS
Free-standing spring isolators are unhoused laterally stable steel springs.
They provide a minimum horizontal stiffness of 0.8 times the rated vertical
stiffness and provide an additional 50% overload capacity. These isolators
are equipped with a top-mounted adjusting bolt and an acoustical non-skid
base. Springs are color-coded or identified to indicate load capacity.
