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. 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.
Polyurethane bumpers have better abrasion resistance than SBR bumpers. They won't become brittle and crack when exposed to ozone, are nonmarking, and can be used outdoors.
Neoprene bumpers have good abrasion resistance. They can be used outdoors.

Adhesive-Back Bumpers
Press these bumpers into place with the adhesive backing. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. They're comparable to Bumpon bumpers.
Bumpers with a medium and medium-soft rating offer a balance of cushioning and impact resistance. The softer the bumper, the more it cushions. Bumpers with an extra-hard and medium-hard rating withstand higher levels of impact than softer bumpers. The harder the bumper, the more impact it withstands.
Polyurethane bumpers have good abrasion resistance. They're also nonmarking.

Fixturing Tables
Add components such as clamps, brackets, stops, rests, mounting plates, fixturing squares, risers, and V-blocks to build fixtures for welding and assembly.
Tables have removable plates that are precision ground to a tight tolerance for accurate positioning. Holes in a grid pattern and slots between the plates support a variety of clamps or workholding setups.
