These carriages and guide rails are steel.

Suitable for clean room use, these carriages and guide rails are made entirely of stainless steel.

A plastic cage separates the ball bearings to minimize noise, reduce heat buildup, and eliminate ball collisions.

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.

With a larger contact area than ball bearing carriages, roller bearing carriages provide better positioning accuracy and support heavier loads.
