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

Protective Covers for Conveyor Rollers
Reduce noise, absorb impact, and extend roller life. The higher the hardness rating, the longer the covers will protect rollers in demanding applications.
Slide-on covers slip over the roller. For easier installation, use lubricant and an air nozzle.
Polyurethane has a high-friction surface for high speeds and inclines.
Lubricant is water based and loses its lubrication properties upon drying to ensure covers retain a snug fit.
Connect air nozzles to a source of compressed air to create a cushion for sliding covers onto the roller.

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

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. 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. All rollers are permanently lubricated.
Rollers with seal have an end seal to protect the rolling elements from dirt and contamination.

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

Roller Track for Doors
Combine track, mounting brackets, hangers, and end stops to create a system for hanging doors.
For technical drawings and 3-D models, click on a part number.
Choose a hanger that fits your inside track width. These hangers are sold individually and come with bolts to attach to the door. They adjust vertically within the bolt's thread length. Hangers with more rollers distribute heavy loads more evenly, giving your door more support and smoother movement. Two hangers per door are required.
