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.

With Seal—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.

440C Stainless Steel Rollers—440C stainless steel rollers offer better corrosion resistance than steel rollers.

With Seal—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.

Plastic Overmold—Rollers with a plastic overmold make less than noise than other rollers, and they’re suitable for corrosive environments. However, they have lower weight capacities than other similarly sized rollers and they’re less corrosion resistant than other stainless steel rollers.

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.

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.

Double Sealed and Shielded—Double-sealed rollers are better protected from high-pressure liquid and debris than single-sealed rollers, and also operate within a broader temperature range. They’re built to withstand the frequent high-pressure, high-temperature washdowns found in food and pharmaceutical plants.

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.

Fixed Shoulder—Rollers with a fixed shoulder have a threaded mounting stud. Thread them directly into a component, or secure them with a nut for through-hole mounting.

Adjustable Shoulder—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.
