11mm Wide Rollers | McMaster-Carr

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.

Track lubricators reduce friction and wear without shutting down equipment. Oil-infused resin distributes lubricant onto rollers, which transfer it to your track.

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.

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.

Track lubricators reduce friction and wear without shutting down equipment. Oil-infused resin distributes lubricant onto rollers, which transfer it to your track.

Threaded 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. Secure the stud with a nut for through-hole mounting. All rollers have end seals to protect rolling elements from 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.

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 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.

Tapered Stud Track Rollers

Roller

Grease Fitting

Install these rollers in worn-out mounting holes or where you don’t have access to the back of the mounting hole. The stud is tapered, so you can quickly secure them in place with a set screw (not included) instead of a nut on the back like traditional rollers. Keep in mind, this reduces their radial capacity.

Rollers with a seal protect rolling elements from dirt and contamination better than shielded rollers, but they do hold more heat. The seal also helps retain lubrication.

Add a grease fitting to create a lubrication point.

Threaded V-Groove Track Rollers

External Hex Shoulder Drive

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 offer better corrosion resistance than steel rollers.

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.

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.

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.
