Rubber bumpers and urethane bumpers are designed to guard, stop, align, and protect a machine or work piece during the manufacturing process. They are available in round, square, and rectangular shapes (custom sizes available) with a variety of different styles that can integrate well into any application.

These bumpers are available in black neoprene, white nitrile, or colored urethane, each with varying durometers. Each material has a number of advantages associated to it, which are illustrated in the table below:

Urethane
Highest available abrasion resistance, strength & load bearing. High elongation, hardness. Resistant to ozone, oxygen.

Nitrile (Buna-N)
Resistant to gasoline, oil, alcohol, abrasion. Good physical properties.
