Shaft-Mount V-Groove 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 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. All rollers are permanently lubricated.
Sealed rollers block out dust and other contaminants better than shielded rollers, but they hold more heat. Their seals also help retain lubricant.

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.

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.

Sanitary Shaft-Mount V-Groove Track Rollers


Support and guide loads on angle rails in food, pharmaceutical, and other sanitary environments. Also known as yoke-style cam followers, these track rollers offer more mounting flexibility than threaded alternatives and are typically mounted on shafts and clevis rod ends. They’re permanently lubricated to prevent contamination, with sealed and shielded bearings blocking out debris and liquids to protect the lubricant. FDA compliant and NSF registered H1, the lubricant is safe for incidental contact with food. These track rollers are made of stainless steel, so they won’t corrode from frequent washdowns with harsh cleaners.

Sanitary Threaded V-Groove Track Rollers


Guide loads along angle rail tracks in food and pharmaceutical plants or other sanitary environments with these threaded rollers. They’re permanently lubricated, a feature often seen in sanitary areas where repeated lubrication could cause contamination. Their lubricant is NSF registered H1 as safe for incidental contact with food. They’re made of stainless steel, so they won’t corrode from frequent washdowns with harsh cleaners. The bearings are sealed and shielded to keep out liquid and make sure the lubricant stays intact. These rollers have a V-groove profile, which allows debris to fall off when they’re mounted on angle rails. They’re also known as cam followers.
Rollers with a standard shoulder have a threaded mounting stud. Thread them directly into a component, or secure them with a nut for through-hole mounting.
Rollers with an adjustable shoulder are also known as eccentric track rollers. They can be moved up and down, and they’re commonly used alongside standard rollers to correct misalignment. Secure them with a nut for through-hole mounting.
