About Durometer Hardness Scales

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.

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.

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.

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.

Load-Rated Threaded Bumpers

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.

Bumper Assortments

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