Heavy Duty Threaded-Stud Bumpers
1
2
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.

Twist these bumpers into a threaded hole. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces.
Bumpers with a medium-soft rating offer a balance of cushioning and impact resistance.
Bumpers with a hard and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
SBR bumpers have good abrasion resistance. They're also nonmarking.
Polyurethane bumpers have better abrasion resistance than SBR bumpers. They won't become brittle and crack when exposed to ozone.
