    These bumpers absorb impact to protect equipment, walls, and floors from dents and scuffs. They're found everywhere from access panels to the bases of equipment. The rubber construction also stifles noise and absorbs vibration to prevent wear and tear to your machinery and nearby surfaces. No separate fasteners are needed—just twist them into a threaded hole.

    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.
    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.

    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 2,000-pound air compressor. All have a metal base plate for added strength and a longer service life than all-rubber bumpers. Twist them onto a threaded stud on your equipment, or pair them with your own stud to create a custom-length bumper.

    Vibration-Damping Sandwich Mounts with Stud and Insert

    Install these mounts between a threaded stud and a hole inside or under equipment. Our jack-of-all-trades option, they isolate vibration to protect circuit boards, air compressors, and everything in between. They also muffle noise so you can work or hold a conversation around buzzing and thumping machinery.

    Vibration-Damping Ring Sandwich Mounts

    These install as easily as other sandwich mounts, and the open-ring design absorbs more of the slow, rumbling vibrations caused by vehicles and slow-moving machinery. Secure them between two holes to protect key components from vibration and keep noise levels manageable. With reinforcing metal bonded to the rubber, they'll support weight whether mounted underneath equipment (Cap. per Mount) or side mounted (Shear Cap. per Mount).
