12mm Wide Rollers | McMaster-Carr

The surface of these rollers is molded to a tolerance of either ±0.003 in. or ±0.08 mm to provide more consistent surface contact. Also known as contact wheels and feed rollers, they have tapped hubs that allow you to mount them onto a shaft or stud to transmit power. The urethane rubber surface is nonmarring and wear resistant.

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.

Roller-Mount Track Lubricators—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 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.

Roller-Mount Track Lubricators—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.

Tapered Stud Track Rollers

Roller

Grease

Fitting

Add a grease fitting to create a lubrication point.

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.

With Seal—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.
