About Track Rollers

Find tubing with the right shrink ratio, flexibility, and dielectric strength. Plus, compare materials by chemical resistance temperature, and more.

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. Lubricate rollers through a hole and groove in the inner ring.

Crowned Roller Profile—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.

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

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. Some rollers have end seals to block dirt and contamination.
