30mm Wide Rollers | McMaster-Carr

With a double row of cylindrical roller bearings, these rollers provide the highest combination of speed and dynamic radial load ratings of any shaft-mount track roller we offer. 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.

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.

Without Seal—Lubricate rollers without seal through a hole and groove in the inner ring.

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 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.

Flanged Threaded Track Rollers

Thread the stud directly into a component or secure with a nut for through-hole mounting. The flange provides guidance and helps the roller stay on track. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.
