Heavy Duty Threaded-Stud Bumpers
All of these bumpers are reinforced with a steel core 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. Twist them into a threaded hole. All are nonmarking and can be used outdoors.
Bumpers with a hard rating withstand high levels of impact. Bumpers with a medium-soft rating offer a balance of cushioning and impact resistance.
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.
Style 2 bumpers have a hex shoulder for easier tightening.

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 soft rating offer cushioning.
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 Vibration-Damping Sandwich Mounts with Studs
Use these rubber sandwich mounts to minimize vibration between surfaces inside machinery and equipment, such as in circuit boards, small fans, compressors, and pumps. They're for use in compression and shear load applications.
Neoprene rubber has good resistance to weather and acids and moderate resistance to oils.
Natural rubber has superior resistance to tears and abrasion as well as good flexibility in cold temperatures.

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.
