975 rpm Bearings | McMaster-Carr

Thread the stud directly into a component or secure with a nut for through-hole mounting. 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. Also known as cam followers, track rollers support loads while guiding and positioning work. All rollers are permanently lubricated.

Rollers with a plastic overmold make less than noise than other rollers, and they’re suitable for corrosive environments. However, they have lower weight capacities than other similarly sized rollers and they’re less corrosion resistant than other stainless steel rollers.

Threaded V-Groove Track Rollers with Adjustable Shoulder

Also known as eccentric track rollers, the shoulder adjusts up or down to align to your track, enabling uniform alignment among rollers in a system. 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. Secure the stud with a nut for through-hole mounting. All rollers are permanently lubricated.

440C stainless steel rollers offer better corrosion resistance than steel rollers.
