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.
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're also nonmarking.

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.

General Purpose Vibration-Damping Sandwich Mounts with Stud and Insert
Use these rubber sandwich mounts to minimize vibration between surfaces inside machinery and equipment, such as in circuit boards, small fans, compressors, and pumps. They're for use in compression and shear load applications.
Neoprene rubber has good resistance to weather and acids and moderate resistance to oils.
Natural rubber has superior resistance to tears and abrasion as well as good flexibility in cold temperatures.
