About Track Rollers

Also known as cam followers, track rollers have a thick outer roller that runs directly on a flat surface.

Threaded Track Rollers

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.

High-Load Threaded Track Rollers

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.

Maintenance-Free Threaded Track Rollers

Because they never need to be relubricated, these rollers are a good choice for hard-to-reach places.

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.

Miniature High-Load Threaded Track Rollers

Despite their size, these rollers handle high radial load capacities without sacrificing speed.

Ultra-Quiet Threaded Track Rollers

The soft rubber or plastic surface on these rollers creates less noise than the metal surfaces found on other track rollers.

Thrust-Load-Rated Threaded Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously.

Extreme-Temperature Threaded Track Rollers

Lubricated with graphite, these rollers can handle temperatures from -450° to 750° F—the widest temperature range of any track roller in our offering.

Miniature High-Speed Threaded Track Rollers

Built to handle high speeds for their size. These track rollers have an outer ring that supports higher speeds than standard-sized track rollers.

Thrust-Load-Rated Corrosion-Resistant
Threaded Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously.

Corrosion-Resistant Threaded Track Rollers

These threaded track rollers are made of materials that prevent corrosion in wet environments.

Maintenance-Free Ultra-Corrosion-Resistant
Threaded Track Rollers

With dry-running PTFE sleeve bearings, these rollers don’t require lubricant. They’re also fully submersible, nonsparking, and lightweight.

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.

High-Load Shaft-Mount Track Rollers

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.

Corrosion-Resistant Shaft-Mount Track Rollers

Made of 440C stainless steel, these shaft-mount track rollers resist corrosion in damp environments.

Thrust-Load-Rated Shaft-Mount Track Rollers

These rollers are rated to handle radial and thrust (top and side) loads simultaneously.

High-Speed Shaft-Mount Track Rollers

The outer ring is built to handle higher speeds than standard shaft-mount track rollers.

Tapered Stud Track Rollers

Install these rollers in worn-out mounting holes or where you don’t have access to the back of the mounting hole. The stud is tapered, so you can quickly secure them in place with a set screw instead of a nut on the back like traditional rollers.

V-Groove Track Rollers

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.

Threaded V-Groove Track Rollers

Thread the stud directly into a component or secure with a nut for through-hole mounting.

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.

Angle Rails for V-Groove Track Rollers

Use these rails with any track rollers that have a 90° V-groove.

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.

Sanitary Threaded V-Groove Track Rollers

Guide loads along angle rail tracks in food and pharmaceutical plants or other sanitary environments.

Flanged Track Rollers

Flanged Threaded Track Rollers

Thread the stud directly into a component or secure with a nut for through-hole mounting.

Flanged Shaft-Mount Track Rollers

Shaft-mount track rollers have more mounting flexibility than threaded track rollers.

Double-Flanged Track Rollers

A dual-flange design provides guidance on both sides and helps these rollers stay on track.

Carriages and Guide Rails

Track Rollers and Guide Rails

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

Light Duty Track Rollers and Guide Rails

Nylon rollers and aluminum rails make these good for light duty applications.

Corrosion-Resistant Track Rollers and Guide Rails

Made of stainless steel, these track rollers and guide rails are more corrosion resistant than steel rollers and rails.

Side-Mount Track Roller Carriages and Guide Rails

Mount along a wall or other vertical surface.

Self-Aligning Side-Mount Track
Roller Carriages and Guide Rails

Create a self-aligning carriage and guide rail system to compensate for mounting surfaces that aren't parallel.

Corrosion-Resistant Side-Mount Track
Roller Carriages and Guide Rails

These track roller carriages and guide rails are stainless steel for use in wet, corrosive environments.

Light Duty Side-Mount Track
Roller Carriages and Guide Rails

Use these carriages and guide rails for light loads where precise movement is not required.

Track Roller Carriages and Guide Rails

V-shaped rollers and rails allow these carriages to operate well in dirty environments because the debris won't get trapped on the rail.

High-Temperature Track Roller
Carriages and Guide Rails

High-temperature PTFE-thickened grease enables these carriages to operate in temperatures up to 500° F, higher than any other carriage that we offer.

Light Duty Track Roller Carriages and Guide Rails

Nylon rollers provide low-friction movement for light loads and corrosive environments.

Side-Mount Track Roller
Carriages for T-Slotted Framing

Combine with a T-slotted rail to add linear motion to your assembly.

High-Load Track Roller Carriages and Guide Rails

Needle-roller bearings give these track roller carriages higher load capacities than other track roller carriages.

Locking High-Load Track Roller
Carriages and Guide Rails

A handle on the side of the carriage locks the carriage in place.

Self-Aligning Low-Profile Sleeve
Bearing Carriages and Guide Rails

Compensate for rail misalignment in low-clearance applications with these carriages and guide rails.

Self-Aligning Sleeve Bearing
Carriages and Guide Rails

A floating bearing in these self-aligning carriages adjusts to compensate for misalignment between rails, so your carriages still move in tandem.

Self-Aligning Locking Sleeve
Bearing Carriages and Guide Rails

Create a self-aligning system that can be locked in place with these carriages and guide rails.

Building and Machinery Hardware

Track Rollers

Use these rollers as replacements on an existing door hanger or as the starting point for a customized hanger.
