Style 1 |
Tested to ensure they’ll bear the weight of your application, these bumpers support everything from a 50-pound saw to a 2,000-pound air compressor. They also help reduce vibration and protect whatever they're mounted to. All have a metal base plate for added strength and a longer life than all-rubber bumpers. Twist them onto a threaded stud on your equipment, or pair them with your own stud to create a custom-length bumper.

Style 1 |
Our toughest rubber bumpers, they keep their shape even when knocked and scraped by metal and other abrasive materials. They're often used on industrial vehicles, conveyors, and heavy construction equipment.
Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.
