    Reinforced Threaded-Hole Bumpers

    Image of Product. Front orientation. Bumpers. Reinforced Threaded-Hole Bumpers, Style 1.

    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.

    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.

    Vibration-Damping Sandwich Mounts with Inserts

    Install these mounts between studs 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. 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).

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

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

    Image of Product. Front orientation. Leveling Mounts. Easy-Install Vibration-Damping Swivel Leveling Mounts with Threaded Stud, With Cushion.

    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.
