    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.

    Keep equipment level on slightly sloped and pitted floors with mounts that have a ball-and-socket joint in the base. For mounting versatility, you can install them in either threaded holes or unthreaded through holes at the bottom of equipment.
    Nickel-Plated Steel Base—With a shiny appearance, these mounts create a finished look. They're best for dry environments since the nickel plating offers minimal corrosion resistance.
    Zinc-Yellow-Chromate-Plated Steel Base—More corrosion resistant than nickel-plated steel, these mounts are suitable for damp environments. However, they won’t hold up to chemical cleaners, high-pressure washdowns, and other harsh conditions like stainless steel can.
    Black-Oxide Steel Base—With a matte black appearance, these mounts create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
    303 Stainless Steel Base—The choice for most wet locations, these mounts can withstand repeated washdowns without corroding. However, they won't hold up to cleaning solutions that contain harsh chemicals like 316 stainless steel can.
    316 Stainless Steel Base—Our most corrosion-resistant metal mounts, these hold up in just about any environment. They won’t degrade or become pitted, even when exposed to harsh cleaners and chemicals.
    Delrin® Acetal Base—These mounts are economical yet resistant to grease, oil, and chemicals that pool on the floor. Often used on small, lightweight machines, they have about 25% the capacity of similarly sized metal mounts.
    Rubber Cushion—A cushion under the base grips surfaces so vibrating equipment doesn't slide. It also protects floors from scrapes and gouges.

    Bolt down machines so they don’t creep across the floor or tip over. These mounts have punch-out holes for securing equipment that you don’t need to move. The ball-and-socket joint in the base swivels to compensate for slightly sloped and pitted floors. For mounting versatility, you can install these mounts in either threaded holes or unthreaded through holes at the bottom of equipment.

    Cushioned Solid-Surface Grippers

    Topped with textured urethane, these grippers hold workpieces steady without digging into the surface. They’re often used to support finished parts and oddly shaped workpieces. Rather than a through hole, these grippers have a solid surface that grips your workpiece evenly and shields the mounting hole from debris. However, they can be harder to line up than grippers with a through hole. Mount them from the bottom with a socket head cap screw.
    The lower the durometer of the gripper surface, the more cushion it provides; the higher the durometer, the more wear it can withstand over time.

    Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005". Components are compatible with Jergens Ball-Lock, Carr-Lane Carr Lock, and Kurt PinLock quick change systems.
    For accurate positioning, at least two sets of clamps, liners, and receivers are required. Install the receivers in the base plate and the liners in the fixture plate. Then line up the two plates, insert the clamps, and tighten their screws to secure the fixture in place. If more holding capacity is needed, use additional clamps and receivers but omit liners to prevent the clamp from getting stuck in the fixture plate.

    Tested to ensure they’ll bear the weight of your application, these bumpers support everything from a 50-pound saw to a 2,000-pound air compressor. They also help reduce vibration and protect whatever they're mounted to. All have a metal base plate for added strength and a longer 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.

    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.
