About Track Rollers
Also known as cam followers, track rollers have a thick outer roller that runs directly on a flat surface.

Thrust-Load-Rated Corrosion-Resistant Threaded Track Rollers
These rollers are rated to handle radial and thrust (top and side) loads simultaneously. 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. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.
303 stainless steel rollers are more corrosion resistant than 440C stainless steel rollers.

Miniature High-Speed Threaded Track Rollers
Built to handle high speeds for their size. These track rollers have an outer ring that supports higher speeds than standard-sized track rollers. They also create less friction than miniature high-load rollers while spinning. You can use these rollers for precise movements in robots or other miniature applications.

Threaded V-Groove Track Rollers
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 seal block out dust and other contaminants better than shielded rollers, but they hold more heat. Their seal also helps retain lubricant.
