Load-Rated Threaded-Stud Bumpers




Select these bumpers for applications that require specific load capacities. All are reinforced with a 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 and conveyors. Twist these bumpers into a threaded hole.
Bumpers with a medium hardness rating offer a balance of cushioning and impact resistance.
Rubber bumpers are abrasion resistant. Those with a soft rating can be used outdoors.
Buna-N bumpers withstand a wider range of temperatures than other bumpers and resist abrasion, oil, and grease.
Stainless steel studs are more corrosion resistant than steel studs.

Threaded-Stud Bumpers


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 hard and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
Polyurethane bumpers have better abrasion resistance than SBR bumpers. They won't become brittle and crack when exposed to ozone.

Heavy Duty Unthreaded Bumpers

All of these bumpers are reinforced with an embedded washer 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. Install them with screws. These bumpers are also known as recessed bumpers.
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 are not for use outdoors.
Polyurethane bumpers have better abrasion resistance than SBR bumpers. They won't become brittle and crack when exposed to ozone, are nonmarking, and can be used outdoors.
Plastic bumpers are chemical resistant and won't dry out and become brittle when exposed to UV rays. They are nonmarking and can be used outdoors. These bumpers are not rated for durometer.

Tight-Grip Push-In Bumpers


A ridge on the stem provides a tighter grip than other push-in bumpers. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.
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 are not for use outdoors.
