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.

High-Load Shaft-Mount Track Rollers


With Seal	Without Seal

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.

With Seal—Rollers with seal are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

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

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.

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.

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.

High-Speed Shaft-Mount Track Rollers

The outer ring is built to handle higher speeds than standard 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.

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