    About Vibration-Damping Mounts
    industrial info icon

    Choose the right vibration-damping mounts to protect equipment from damage and reduce noise.

    Seismic Vibration-Damping Mounts

    Offset shock and vibration under normal conditions while preventing sheared bolts and other costly damage during an earthquake. With two rows of bolt holes and a steel covering to remain rigid and stable, these mounts withstand 1g of lateral force. Ideal for large industrial machinery, they stay rigid and strong under loads of up to 3,500 pounds.

    Resist wear and tear well enough for most applications. They won't break down when exposed to oil, grease, and gasoline, so they're a good choice for motors and pumps.
    Steel Base and Cadmium-Plated Steel Bolt—The cadmium adds lubricity so the bolt threads on smoothly and won’t seize or gall if you need to adjust the height of your equipment.

    Seismic Stay-Put Swivel Leveling Mounts with Threaded Stud

    Subjected to rigorous stress tests, these mounts withstand movement in every direction to minimize damage during an earthquake. After leveling your machine, bolt the mount to the floor and tighten the locking nut onto the base for added stability. The ball-and-socket joint in the base swivels to compensate for slightly sloped and pitted floors. For mounting versatility, you can install these mounts in either threaded holes or unthreaded through holes at the bottom of equipment.

    With Cushion

    304 Stainless Steel Base—The choice for most wet locations, these mounts can withstand repeated washdowns without corroding. However, they won't hold up to cleaning solutions that contain harsh chemicals like 316 stainless steel can.
    Rubber Cushion—A cushion under the base protects floors from scrapes and gouges.
