    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.

    Self-Adjusting Shock Absorbers

    Accommodate changing loads and energy without manual adjustment. Shock absorbers counteract the energy of moving objects to prevent damage to equipment and material. They're often used in gantry systems, presses, and at stops along conveyors. Mounting nuts are included. Mounting Blocks for Shock Absorbers are sold separately.

    Adjustable Air Springs

    Isolate vibration and absorb shock from moving equipment, even with changing loads. Also for leveling and lifting, use compressed air to adjust air springs to the height and force required for your application. They’re often used with vibratory screen and conveyors; loading and transfer stations; and sensitive testing and measuring equipment. Do not extend beyond height at full stroke.

    Corrosion-Resistant Self-Adjusting Shock Absorbers

    Made from stainless steel for excellent corrosion resistance in damp environments. Install shock absorbers in gantry systems, presses, and at stops along conveyors—they counteract the energy of moving objects to prevent damage to equipment and material. Use Mounting Blocks for Shock Absorbers (not included) and Mounting Nuts for Shock Absorbers (not included) for mounting.

    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.
