About Vibration-Damping Mounts

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

Shock-Absorbing Spring Vibration-Damping Mounts

Absorb higher-intensity shocks and vibration than mounts without springs. These mounts compress (deflect) four times farther than other mounts when force is applied to protect shaking, thudding machinery and nearby equipment. They also dissipate the low, slow-moving vibrations other mounts can't handle, such as the rumbling of traffic or a large air compressor. With a durable antislip base that secures equipment without the help of fasteners, these mounts are ideal for floors you can't drill into and equipment without bolt holes.

Mount

If you can't drill bolt holes into your equipment or floor, use these ribbed, antislip mounts without fasteners.

Multipurpose Neoprene—Resist wear and tear well enough for most applications. They are UV resistant and won't break down when exposed to oil, grease, and gasoline, so they're a good choice for motors and pumps.

Mount

These low-profile mounts isolate vibration around wiring, circuit boards, and other components installed in narrow gaps. Install a washer to support equipment and avoid costly downtime if the rubber fails.

Natural Rubber—The most common choice, these mounts won't scuff or tear easily. They stay strong and flexible even under constant vibration and repeated movement.

Aluminum Base—Won't weaken and rust as quickly as steel when exposed to moisture and chemicals.

Any-Orientation Fail-Safe Vibration-Damping Bolt-Down Mounts


Style 1, Threaded-Insert Mount	Style 2, Threaded-Insert Mount

Dampen vibration in any orientation. Unlike traditional mounts that may fail when installed in the wrong position, these support the same load capacity no matter how they’re mounted. Also known as all-attitude mounts, they’re often used in aerospace and aviation to handle unpredictable motion. Even if the rubber fails, the steel body holds up to support the load and minimize downtime while you find a replacement. To install on equipment, bolt through the threaded insert. Secure mounts to the support structure using the holes in the flange.

Style 1—Threaded-Insert Mount


	Style 1, Threaded-Insert Mount

A zinc-plated steel cover guards the neoprene insert from dust, oil, and moisture, extending the mount’s life. The enclosed, cup-style design spreads shock forces evenly to protect sensitive equipment.

These mounts are designed to fit into cutouts, giving them a lower profile than Style 1 mounts. They’re often used to mount lightweight electronics and computers in military vehicles, aircraft, and construction equipment.

High-Temperature Silicone Rubber—These mounts handle temperatures about twice as high as natural rubber and neoprene. They also handle temperatures well below zero for the widest temperature range of any mount we offer.

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.

Shock-Absorbing Air Spring Vibration-Damping Mounts

Neutralize shock and vibration from your machine no matter how hard it heaves or hammers. These mounts use air pressure rather than a steel frame to support a load. That means four times the deflection and vibration control of a typical bolt-down mount. Fill them with air and stick them under heavy machinery to keep floors intact, seals tight, and fasteners secure. They’ll also soak up the vibration from floors and mounting plates that bumps optical and other precision tools out of alignment.

Easy-Install Vibration-Damping Rigid Leveling Mounts with Threaded Stud

Style 2

A two-piece design requires less clearance to install than one-piece mounts. Install these mounts in threaded holes to level equipment on uneven floors. Use a locknut (not included) to install mounts in unthreaded through holes. A rubber cushion reduces vibration to protect components and extend your machine’s life.

Aluminum Base—These mounts are lighter than stainless steel ones, reducing the overall weight of your machine. They withstand occasional exposure to moisture, but don't hold up in wet environments like stainless steel.

Rubber Cushion—In addition to reducing vibration, the cushion grips surfaces so vibrating equipment doesn't slide. It also cuts down on noise and protects floors from scrapes and gouges.
