2 1/4" 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.

High-Load Threaded Track Rollers

Black-Oxide Steel

With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any threaded track roller we offer. 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. All rollers are permanently lubricated.

Crowned rollers have a slight curve, invisible to the naked eye, which helps them stay centered on surfaces that are slightly misaligned or not perfectly flat.

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

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.

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

Thrust-Load-Rated Shaft-Mount Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously. Also known as yoke-style cam followers, they have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

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.

Flanged Shaft-Mount Track Rollers

Shaft-mount track rollers have more mounting flexibility than threaded track rollers. Because they’re flanged, they can handle both radial and thrust (top and side) loads. The flange also provides guidance and helps rollers stay on track. All are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.
