About Leveling Mounts

Choose the right leveling mounts for your floor conditions, equipment weight, and vibration-control needs.

Swivel Leveling Mounts with Threaded Stud

With Cushion

Without Cushion

Keep equipment level on slightly sloped and pitted floors with mounts that have a ball-and-socket joint in the base. For mounting versatility, you can install them in either threaded holes or unthreaded through holes at the bottom of equipment.

303 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.

316 Stainless Steel Base—Our most corrosion-resistant metal mounts, these hold up in just about any environment. They won’t degrade or become pitted, even when exposed to harsh cleaners and chemicals.

Nickel-Plated Steel Base—With a shiny appearance, these mounts create a finished look. They're best for dry environments since the nickel plating offers minimal corrosion resistance.

Zinc Yellow-Chromate-Plated Steel Base—More corrosion resistant than nickel-plated steel, these mounts are suitable for damp environments. However, they won’t hold up to chemical cleaners, high-pressure washdowns, and other harsh conditions like stainless steel can.

Rubber Cushion—A cushion under the base grips surfaces so vibrating equipment doesn't slide. It also protects floors from scrapes and gouges.

Stay-Put Swivel Leveling Mounts with Threaded Stud

Bolt down machines so they don’t creep across the floor or tip over. These mounts have one or more punch-out holes for securing equipment that you don’t need to move. 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.

Vibration-Damping Swivel Leveling Mounts with Threaded Stud

A rubber cushion reduces vibration to protect components and extend your machine’s life. These mounts have a ball-and-socket joint in the base that swivels to compensate for slightly sloped and pitted floors. For mounting versatility, you can install them in either threaded holes or unthreaded through holes at the bottom of equipment.

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—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.

Shock-Absorbing Swivel Leveling Mounts with Threaded Stud

Often used on presses, lathes, and die cutters, these mounts protect machines and floors from damage when equipment suddenly starts and stops. They have a solid rubber base, similar to a hockey puck, that isolates shock. The base also cuts down on noise and grips the floor so equipment doesn't slide when it's vibrating. 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.

Reinforced Threaded-Stud Bumpers

Style 1

With a metal core for added strength, these bumpers withstand repeated impacts for a longer service life than all-rubber bumpers. You can also use them as spacers, vibration dampers, and noise reducers. No separate fasteners are needed—just twist them into a threaded hole.

Style 1

Multipurpose Neoprene—A good choice for oily equipment that's exposed to sunlight, rain, and ozone. These aren't as oil resistant as Buna-N bumpers, but they can be used outdoors.

Abrasion-Resistant Polyurethane Rubber—Our toughest rubber bumpers, they keep their shape even when knocked and scraped by metal and other abrasive materials. They're often used on industrial vehicles, conveyors, and heavy construction equipment.

Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.

Load-Rated Reinforced Threaded-Stud Bumpers

Style 1

These bumpers are tested to ensure they'll support the load of your application. They'll bear the weight of everything from a 50-pound saw to a 5,000-pound air compressor. All have a metal base plate for added strength and a longer service life than all-rubber bumpers. No separate fasteners are needed—just twist them into a threaded hole.

Style 1

Natural Rubber—These bumpers absorb impact well enough for most applications. However, they're not for use outdoors and break down when exposed to oil and harsh chemicals.

Stainless Steel Stud—Unlike bumpers with steel studs, these handle repeated washdowns without corroding.

Steel Stud—Durable and economical, these are the choice for most jobs.
