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 soft and extra-soft rating offer cushioning. The softer the bumper, the more it cushions.
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.
Polyurethane bumpers have better abrasion resistance than rubber bumpers. They won't become brittle and crack when exposed to ozone.
