Abrasion-Resistant Flex-Grip Drive Rollers
These urethane 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 rollers have larger sidewall holes than flexible rollers, so they compress more and better protect delicate material.

Abrasion-Resistant Keyed Drive Rollers
These urethane 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.
Note: The hub on rollers with 1 1/2" to 4" roller diameter protrudes on one side only.
