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

Permanently Lubricated Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

Maintenance-Free Threaded Track Rollers
Because they never need to be relubricated, these rollers are a good choice for hard-to-reach places. 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 have end seals to block dirt and contamination.
Crowned rollers have a slight curve, which is invisible to the naked eye, to stay centered on surfaces that are not perfectly aligned and/or not perfectly flat.

High-Speed Shaft-Mount Track Rollers
The outer ring is built to handle higher speeds than standard shaft-mount track rollers. Also known as yoke-style cam followers, these rollers have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end.
Rollers with seal have end seals to protect rolling elements from dirt and contamination.

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.
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.
