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

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.
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.

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.

High-Load Shaft-Mount Track Rollers
With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any shaft-mount track roller we offer. 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.
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.
Lubricate rollers without seal through a hole and groove in the inner ring.
