High-Load Shaft-Mount Track Rollers


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.

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

Threaded V-Groove Track Rollers

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.

With Seal—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.
