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. 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. The urethane surface is nonmarring and wear resistant.

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.
Rollers with seal have end seals to protect rolling elements from dirt and contamination.
