About Durometer

Durometer is the international standard for measuring the hardness of rubber, plastic, and most nonmetallic materials.

Tight-Tolerance Drive Rollers

The surface of these rollers is molded to a tolerance of either ±0.003 in. or ±0.08 mm to provide more consistent surface contact.

Abrasion-Resistant Drive Rollers

These urethane rollers are nonmarring and wear resistant.

Drive Rollers

Made of neoprene rubber, these rollers resist oil, flames, gasoline, and weather.

Abrasion-Resistant Low-Profile Drive Rollers

The mounting holes on these rollers are tapped directly through the roller’s surface so you can install them with set screws and still fit them into tight spots.

Idler Rollers

Threaded Idler Rollers

Made of neoprene rubber, these rollers resist oil, flames, gasoline, and weather.

Abrasion-Resistant Threaded Idler Rollers

These polyurethane rollers are nonmarring and wear resistant.

Abrasion-Resistant Self-Cleaning Threaded Idler Rollers

These urethane rollers are nonmarring and wear resistant.

Self-Cleaning Threaded Idler Rollers

Made of neoprene rubber, these rollers resist oil, flames, gasoline, and weather.

Abrasion-Resistant Idler Rollers

These urethane rollers are nonmarring and wear resistant.

Idler Rollers

Made of neoprene rubber, these rollers resist oil, flames, gasoline, and weather.

No-Stick Idler Rollers

A slippery UHMW polyethylene surface means these rollers won't stick to adjacent parts. Rollers are also highly corrosion resistant.
