About Durometer Hardness Scales

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.

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.

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.

High-Temperature Load-Rated Threaded-Stud Bumpers

These bumpers withstand temperatures up to 300° F, which is twice as high as our other load rated bumpers. Use them in applications that require specific load capacities. All are reinforced with a base plate for strength. Often used as feet, spacers, and vibration dampers, these bumpers absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Twist them into a threaded hole.

Load-Rated Threaded Bumpers

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.

High-Temperature Load-Rated Threaded Bumpers

These bumpers withstand temperatures up to 300° F, which is at least twice as high as our other load rated bumpers. Use them in applications that require specific load capacities. All are reinforced with a base plate for strength. Often used as feet, spacers, and vibration dampers, these bumpers absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Mount them on a threaded stud.

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.

Load-Rated Unthreaded Bumpers

Select these bumpers for applications that require specific load capacities. 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. Install them with a screw.

Unthreaded Bumpers

Install these bumpers with screws. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces.

Nonslip Unthreaded Bumpers

These nonslip bumpers protect equipment while minimizing the movement of objects that come in contact, making them good for positioning and robotic-gripping applications. Install them with adhesives or screws.

Angle Bumpers

These bumpers are at a 90° angle to protect corners on equipment, walls, and docks from damage caused by carts, vehicles, and other moving objects. Install them with screws.

Load-Rated Adhesive-Back Bumpers

Select these bumpers for applications that require specific load capacities. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. Press them into place with the adhesive backing. They're comparable to Bumpon bumpers.

Adhesive-Back Bumpers

Press these bumpers into place with the adhesive backing. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. They're comparable to Bumpon bumpers.

Cut-to-Size Adhesive-Back Bumpers

Make bumpers the size and shape you need. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. Press them into place with the adhesive backing.

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.

Compressible-Stem Push-In Bumpers

The stem on these bumpers compresses to fit into tight holes. 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.

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.

Bumper Assortments

Keep bumpers of various shapes, materials, and mounting styles on hand to solve whatever problems arise.

Tack Bumpers

Install with a few taps of a hammer. In addition to protecting soft materials such as wood, fiberboard, and plastic, these bumpers are commonly used on table and chair legs to safeguard floors.

Magnetic Bumpers

A magnetic base makes it easy to attach, move, and replace these bumpers on metal surfaces. Use them for guarding, aligning, and positioning parts.

Crane Bumpers

Designed to withstand repeated heavy hits on bridge or ceiling cranes, these bumpers protect walls or beams as well as extend crane life.

Springs

Fastener-Mount Compression Springs

Differently sized mounting holes on either side allow for mounting flexibility.

High-Load Fastener-Mount Compression Springs

These springs handle higher loads than standard fastener-mount compression springs. Secure by inserting a fastener through the hole at the base.

Ultra-High-Load Fastener-Mount Compression Springs

For the heaviest loads, these springs have more than double the load capacity of High-Load Fastener-Mount Compression Springs. Secure by inserting a fastener through the hole at the base.

Flanged Compression Springs

Flanges on the ends of these springs provide a flat mounting surface.

Corrosion-Resistant Die Springs

A quieter, more vibration-resistant alternative to traditional steel die springs, these polyurethane springs resist oxidation, oil, and abrasion in high-load, high-pressure applications.
