Spring Isolator Mounts

Mason Industries Spring Isolators

We are the proud supplier of Mason Industries Spring Isolator Mounts across Canada. Mason, a manufacturer of vibration control products for over 60 years, makes top quality vibration isolation products. Continuous innovators, Mason designs and manufactures superior products.

Common uses for Spring Isolator Mounts

Engineers use spring mounts to isolate vibrations generated by rotating and electrical equipment, preventing them from entering the structure. Also known as Spring Vibration Isolators, these mounts combine one or more springs and are placed under the equipment. The spring allows for free oscillation of the equipment with minimal transfer of energy into the structure. In seismic zones, engineers use seismic anti-vibration spring mounts to isolate and secure equipment during earthquakes.

Mason Spring Isolators have numerous equipment applications including:

  • Fan Equipment
  • Air Handling Equipment
  • Fan Heads
  • Blowers
  • Transformers
  • Pumps
  • Utility Sets
  • Compressors
  • Cooling Towers

Free Standing Mason Industries Spring Mounts

Mason produces 2 types of Free Standing Spring Mounts: SLF and SLFH

SLF free standing spring mounts are recommended for use with floor mount equipment to mitigate the transmission of vibrations into the structure. These mounts are designed for stability and do not need to be bolted down to the structure. Where bolting to the structure is required, the SLFH provides bolt holes in the base. These mounts are not recommended for use with equipment that have extreme changes in weight during operation or are subject to seismic and/or wind events.

Single and Multiple Housed Spring Mounts

  • Single and Multiple Housed Spring Mounts are Type “C” mountings. They are specifically designed for noise and vibration free applications in critical areas on light concrete or wooden floors. They provide a packaged solution to troublesome vibration problems.
  • These Single and Multiple Housed Spring Mounts will perform best where it is necessary to establish low natural frequencies. As the static deflection of a spring is greater than most rubber materials, they work well.
  • These spring mounts also work as a mounting that is more yielding than the supporting floor.

Spring Mounts for Seismic and Restrained Service

The SLR and SLRSO Mounts are installed in seismic zones and are used to both isolate and restrain equipment in case of an earthquake.

Housed Single Spring Mounts for Seismic and Restrained Service

These mounts are similar to the SLR and SLRSO, however, they are contained in Ductile Iron Housing. The housing includes a baseplate with either 2 or 4 holes to allow for plug welding or bolting.

Jack Up Spring Mounts

These are concrete inserted, single and multiple spring mounts with side access and top access and hydraulic adjustment. The KIP, KI and KIJ mounts provide many size, rating, dimension and color options.

Free Standing and Restrained Air Springs Mounts

Air Spring Mounts consist of upper and lower steel sections. A replaceable, flexible nylon-reinforced neoprene cover and liner connect these sections. Called a Twin Sphere, this neoprene element comes with a Nylon tire cord reinforcement. Both these systems are connected to either:

  • the building control air or
  • a supplementary air supply and equipped with three levelling valves.

The SLR-MT products feature welded, restrained Twin Sphere Air Spring Mounts. They have plates on the top and bottom with holes for bolts. If you’re not using the mounts for seismic or wind resistance, you don’t need the bolts because the base has a non-skid neoprene friction pad.
