Threaded Bumpers
Mount these bumpers on a threaded stud. All are reinforced with a steel core or base plate for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines. All of these bumpers can be used outdoors.
Bumpers with a medium and medium-soft rating offer a balance of cushioning and impact resistance. The softer the bumper, the more it cushions.
Bumpers with an extra-hard, hard, and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
Buna-N bumpers resist abrasion, oil, and grease.
Neoprene bumpers have good abrasion resistance.
Polyurethane bumpers have better abrasion resistance than neoprene bumpers. They won't become brittle and crack when exposed to ozone.

General Purpose Bolt-Down Vibration-Damping Mounts with Threaded Hole
These mounts bolt to your mounting surface to keep your equipment stationary. Use them in compression load applications with rotating equipment such as fans, blowers, pumps, compressors, and generators.
Neoprene rubber has good resistance to oil and gasoline.

Oil-Resistant Vibration-Damping Mounts with Threaded Hole
Made of nitrile rubber, these mounts are oil resistant for use in compression load applications with punch presses, milling machines, grinders, and air compressors. They have an aluminum plate on top to support heavy loads and displace vibration and shock through the entire mount. The bottom of the mount has hundreds of suction pockets to prevent machine walking. Mounts come with a bolt and nut for height adjustment.

Low-Clearance Swivel Vibration-Damping Leveling Mounts with Threaded Stud
A two-piece design requires less clearance than one-piece mounts and simplifies installation—raise your machine just enough to slide the base underneath, then insert the stud from above. Use these mounts to minimize vibration and noise to prolong machine life and protect floors. The stud rests in an unthreaded depression in the center of the base and swivels to compensate for uneven floors. In addition to leveling, mounts raise equipment off the floor for easier cleaning and inspection. They have a cast iron base that's good for use indoors in dry conditions.
