These carriages and guide rails are steel.

A black chrome plating diffuses light, preventing reflecting light from causing equipment to malfunction.

A plastic cage surrounds the ball bearings and keeps them from colliding, so these carriages run for many cycles without needing maintenance.

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

Small enough to fit in a camera zoom lens and other precision motion applications, these carriages and guide rails have a black chrome-plated finish that diffuses light to prevent reflecting light from causing equipment to malfunction.

With a wide base and low-profile design, these carriages and guide rails stabilize moment (twisting) and off-center loads better than other carriages and rails. They're good for use in areas where multiple carriages or rails won't fit.

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