Reinforced Threaded-Hole Bumpers
 |
Style 1 |
With a metal 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 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.

Style 1 |
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.
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.
Abrasion-Resistant Polyurethane Rubber

Style 1 |
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.

Vibration-Damping Bolt-Down Mounts
 |
Style 1, Threaded-Insert Mount |
These mounts reduce vibration and noise while anchoring machinery from below. Bolt them to the bases of fans, pumps, and generators so vibration from moving components doesn't wear out parts, crack floors, and push equipment out of place.
Style 1—Threaded-Insert Mount
|
Style 1, Threaded-Insert Mount |
The most common choice, these mounts absorb enough shock and vibration for most machinery.
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.

Easy-Install Vibration-Damping Swivel Leveling Mounts with Threaded Stud
 |
With Cushion |
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.
