About Durometer

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

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.

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.

Slim-Tread Drive Rollers

A narrow O-ring tread provides both a sure grip and a delicate touch, making these rollers good for light duty tasks such as those involving paper and tape.

Self-Cleaning Drive Rollers

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

Abrasion-Resistant Self-Cleaning Drive Rollers

These urethane rollers are nonmarring and wear resistant.

Abrasion-Resistant Keyed Drive Rollers

These urethane rollers are wear and chemical resistant. They’re also nonmarring.

Keyed Drive Rollers

Use these SBR rubber rollers with a keyed shaft to prevent slippage in high-torque applications.

Rollers

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

Abrasion-Resistant Rollers
