Style 1 |
With a metal core or base plate 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. Twist them onto a threaded stud on your equipment, or pair them with your own stud to create a custom-length bumper.

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.
Oil-Resistant Buna-N—These bumpers resist oil and fuels better than other rubber bumpers. Use them on frequently lubricated machinery and oily equipment, such as engines and pumps.
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.

Easy-Install Vibration-Damping Swivel Leveling Mounts with Threaded Stud
![]() |
A two-piece design requires less clearance to install than one-piece mounts. Raise your machine just enough to slide the base underneath, then insert the stud from above through a threaded or unthreaded hole. The stud rests in a divot in the base and swivels to keep equipment level on slightly sloped and pitted floors. Mounts also have a rubber cushion that reduces vibration to protect components and extend your machine’s life.
Iron Base—These mounts are best for dry environments since moisture will cause them to rust.
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.

A two-piece design requires less clearance to install than one-piece mounts. Raise your machine just enough to slide the base underneath, then insert the stud from above through a threaded or unthreaded hole to keep equipment level on uneven floors. 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.
