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.
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:
Mason produces 2 types of Free Standing Spring Mounts: SLF and SLFH
When the equipment needs to be securely fastened to the structure, the SLFH mount is a good choice, as it includes bolt holes in the base for easy anchoring. However, these mounts are not recommended for equipment that experience significant weight changes during operation or for installations in areas where seismic activity or strong winds are a concern.
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.
The SLR and SLRSO Mounts are installed in seismic zones and are used to both isolate and restrain equipment in case of an earthquake.
SLR Mounts are general-purpose seismic spring mounts designed to isolate vibration while providing structural restraint in areas subject to seismic or high-wind forces. They feature all-directional neoprene bushings to absorb motion from any direction and maintain a maximum 1/4″ air gap for reliable, stable performance. These mounts are ideal for applications requiring both isolation and restraint in critical environments.
SLRSO Mounts include a robust housing with vertical limit stops to prevent spring overextension when the supported equipment is unloaded. The housing also serves as installation blocking, simplifying setup. Often paired with an SLF mount placed inside the housing, SLRSO Mounts offer enhanced vibration isolation and added protection in seismic installations where both stability and ease of installation are essential.
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.
SSLFH Mounts are seismically restrained spring mounts designed for installations requiring structural anchoring and vertical limit stops. The steel housing includes bolt holes for secure attachment to the building structure and provides vertical restraints to prevent overextension when the equipment is unloaded. These mounts feature a neoprene cushion for all-directional restraint and improved vibration absorption. They deliver reliable performance in areas subject to seismic and wind forces.
SSLFH-X Mounts offer the same seismic restraint and vertical limit stop features as the standard SSLFH but are engineered for applications requiring higher static deflection. With extended spring deflection capability, these mounts provide lower natural frequencies and enhanced vibration isolation.
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:
