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.

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.

Threaded V-Groove 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. 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. Secure the stud with a nut for through-hole mounting. All rollers are permanently lubricated.

Hex Stud-End Drive

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.

Track Rollers and Guide Rails

Support loads while guiding and positioning work with these steel rollers and guide rails.

Steel Track Rollers With Seal


Track Roller	Adjustable Shoulder	Guide Rail

Adjustable Shoulder—Rollers with an adjustable shoulder, also known as eccentric rollers, let you move the roller up and down to align with the track. They're often used alongside rollers with a standard shoulder to correct misalignment.

Carbon Steel—Carbon steel guide rails already have mounting holes drilled.

Sanitary Threaded V-Groove Track Rollers

Guide loads along angle rail tracks in food and pharmaceutical plants or other sanitary environments with these threaded rollers. They’re permanently lubricated, a feature often seen in sanitary areas where repeated lubrication could cause contamination. Their lubricant is NSF registered H1 as safe for incidental contact with food. They’re made of stainless steel, so they won’t corrode from frequent washdowns with harsh cleaners. The bearings are sealed and shielded to keep out liquid and make sure the lubricant stays intact. These rollers have a V-groove profile, which allows debris to fall off when they’re mounted on angle rails. They’re also known as cam followers.

Fixed Shoulder—Rollers with a fixed shoulder have a threaded mounting stud. Thread them directly into a component, or secure them with a nut for through-hole mounting.

Adjustable Shoulder—Rollers with an adjustable shoulder are also known as eccentric track rollers. They can be moved up and down, and they’re commonly used alongside standard rollers to correct misalignment. Secure them with a nut for through-hole mounting.

Corrosion-Resistant Track Rollers and Guide Rails


Track Roller	Standard Shoulder	Guide Rail

Made of stainless steel, these track rollers and guide rails are more corrosion resistant than steel rollers and rails. Mount along a wall or other vertical surface.

Fixed Shoulder—Rollers with a fixed shoulder, also known as concentric rollers, thread directly into a component or insert into mounting hole and fasten with a nut.
