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.

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.

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.

Flanged Threaded Track Rollers

Thread the stud directly into a component or secure with a nut for through-hole mounting. The flange provides guidance and helps the roller stay on track. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.
