Shaft-Mount V-Groove 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. Rollers are for use with Angle Rails for V-Groove Track Rollers. They handle radial and thrust (top and side) loads and work well in dirty environments because debris falls off the angled rail. All rollers are permanently lubricated.
With Seal—Sealed rollers block out dust and other contaminants better than shielded rollers, but they hold more heat. Their seals also help retain lubricant.

1 1/2" to 4" Roller Diameter | 5" to 12" Roller Diameter |
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.

Ultra-Flexible Urethane Rubber Rollers with Aluminum Hub |
These urethane rubber rollers are nonmarring and wear resistant. The 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.
Ultra Flexible—Ultra-flexible rollers have larger sidewall holes than flexible rollers, so they compress more and better protect delicate material.
