About Durometer

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

Drive Rollers

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

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.

Flex-Grip Drive Rollers

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

Abrasion-Resistant Flex-Grip Drive Rollers

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

Oil-Resistant Flex-Grip Drive Rollers

A good choice for oily environments, these Buna-N rollers are also abrasion resistant and nonmarring.

Abrasion-Resistant Rollers

These urethane rollers are nonmarring and wear resistant.

Rollers

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

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.

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.

Press-Fit Low-Profile Drive Rollers

Install these rollers without the need for set screws or keyways.

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.

Abrasion-Resistant Idler Rollers

These urethane rollers are nonmarring and wear resistant.

Abrasion-Resistant Threaded Idler Rollers

These polyurethane rollers are nonmarring and wear resistant.

Threaded Idler Rollers

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

Abrasion-Resistant One-Way-Locking
Threaded Idler/Drive Rollers

These urethane rollers spin freely in one direction and lock to transmit power in the other. They are nonmarring and wear resistant.

One-Way-Locking Threaded Idler/Drive Rollers

These rollers spin freely in one direction and lock to transmit power in the other. Made of neoprene rubber, they are oil, flame, gasoline, and weather resistant.

Track Rollers

Threaded Track Rollers

Also known as cam followers, track rollers support loads while guiding and positioning work. Thread the stud directly into a component or secure with a nut for through-hole mounting.

High-Load Threaded Track Rollers

With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any threaded track roller we offer.

Maintenance-Free Threaded Track Rollers

Because they never need to be relubricated, these rollers are a good choice for hard-to-reach places.

Ultra-Quiet Threaded Track Rollers

The soft rubber or plastic surface on these rollers creates less noise than the metal surfaces found on other track rollers.

Threaded Track Rollers with Adjustable Shoulder

Also known as eccentric track rollers, the shoulder adjusts up or down to align to your track, enabling uniform alignment among rollers in a system.

Thrust-Load-Rated Threaded Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously.

Extreme-Temperature Threaded Track Rollers

Lubricated with graphite, these rollers can handle temperatures from -450° to 750° F—the widest temperature range of any track roller in our offering.

Thrust-Load-Rated Corrosion-Resistant
Threaded Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously.

Maintenance-Free Ultra-Corrosion-Resistant
Threaded Track Rollers

With dry-running PTFE sleeve bearings, these rollers don’t require lubricant. They’re also fully submersible, nonsparking, and lightweight.

Corrosion-Resistant Threaded Track Rollers

These threaded track rollers are made of materials that prevent corrosion in wet environments.

Shaft-Mount Track Rollers

Also known as yoke-style cam followers, these rollers have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end.

High-Load Shaft-Mount Track Rollers

With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any shaft-mount track roller we offer.

Corrosion-Resistant Shaft-Mount Track Rollers

Made of 440C stainless steel, these shaft-mount track rollers resist corrosion in damp environments.

Thrust-Load-Rated Shaft-Mount Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously.

High-Speed Shaft-Mount Track Rollers

The outer ring is built to handle higher speeds than standard shaft-mount track rollers.

Flanged Track Rollers

Flanged Threaded Track Rollers

Thread the stud directly into a component or secure with a nut for through-hole mounting.

Flanged Shaft-Mount Track Rollers

Shaft-mount track rollers have more mounting flexibility than threaded track rollers.

Double-Flanged Track Rollers

A dual-flange design provides guidance on both sides and helps these rollers stay on track.
