High-Load Shaft-Mount Track Rollers


With Seal

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. 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.

With Seal—Rollers with seal are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

These urethane rubber rollers are wear and chemical resistant. They’re also nonmarring. Use them with a keyed shaft to prevent slippage in high-torque applications. Also known as contact wheels and feed rollers, drive rollers spin in unison with a shaft or stud to transmit power.

The hub on rollers with 1 1/2" to 4" roller diameter protrudes on one side only.

Flanged Shaft-Mount Track Rollers

Shaft-mount track rollers have more mounting flexibility than threaded track rollers. Because they’re flanged, they can handle both radial and thrust (top and side) loads. The flange also provides guidance and helps rollers stay on track. All are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

Keyed Drive Rollers


	5" to 10" Roller Diameter	1 1/2" to 4" Roller Diameter

These rollers are made of SBR. Use them with a keyed shaft to prevent slippage in high-torque applications. Also known as contact wheels and feed rollers, drive rollers spin in unison with a shaft or stud to transmit power.

Thrust-Load-Rated Shaft-Mount Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously. Also known as yoke-style cam followers, they have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

Thrust-Load-Rated Threaded Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously. 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. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

Abrasion-Resistant Self-Cleaning Threaded-Stud Idler Rollers

These urethane rollers are nonmarring and wear resistant. Ridges on the surface push dirt and debris out of the way. Commonly found in conveyor systems and printing equipment, they spin freely on an included stud to position and guide work.

Oil-Resistant Flex-Grip Drive Rollers

A good choice for oily environments, these Buna-N rollers are also abrasion resistant and nonmarring. The teardrop-shaped sidewall holes and soft surface allow the roller to gently grab and maintain contact as it is compressed. Also known as contact wheels and feed rollers, these rollers have tapped hubs that allow you to mount them onto a shaft or stud to transmit power.
