About Durometer Hardness Scales

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.

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.

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.

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.

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.

Bumper Assortments

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

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.
