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. Also known as contact wheels and feed rollers, they have tapped hubs that allow you to mount them onto a shaft or stud to transmit power. O-ring is Buna-N, which is nonmarring and resistant to oil and abrasion.
