Guide Rail

With a larger contact area than ball bearing carriages, roller bearing carriages provide better positioning accuracy and support heavier loads. Mount in any orientation without affecting load capacity.

Standard carriages are narrower than flanged carriages, making them better for confined spaces.

Flanged carriages have threaded mounting holes on the flanges rather than the carriage body, so you can fasten loads from both the top and bottom. When fastening from the bottom, use the mounting hole as a through-hole.

Standard Carriages and Guide Rails

For made-to-order guide rails, please specify the length of the rail (in 1 mm increments). The mounting holes will be centered along the rail.
