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. These bumpers are also known as recessed bumpers.
Bumpers with a hard and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
SBR bumpers have good abrasion resistance. They are not for use outdoors.
