About Moment Loads

Miniature Ball Bearing Carriages and Guide Rails

These tiny carriages and guide rails are sized for electronic and other precision applications. They come furnished as a complete unit (a carriage on a guide rail). Mount in any orientation without affecting load capacity.

Note: Ball bearings do not have a cage, so they’ll fall out if the carriage is removed from the guide rail.

Mount 1 mm wd. rails with mounting brackets (sold separately; order one for each end of the guide rail).

Anti-Reflective Miniature Ball Bearing Carriages and Guide Rails

Load Fastening from Top

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. They are also useful in positioning systems that use photosensors, which are sensitive to light. The finish gives you two times more rust resistance than 440 stainless steel alone. The carriage comes already installed on the guide rail. However, the ball bearings don’t have a cage, so they’ll fall out if you remove the carriage from the guide rail. Mount them in any orientation without affecting load capacity.

Telescoping Rail Sets

Create your own positioning table or telescoping slide.

440 Stainless steel rails have a stabilizing gear that won’t fall out of alignment from vibration and sudden shocks, so you don’t have to stop your system to manually realign them. However, they have shorter travel length than standard telescoping rails because of their rack and pinion system.
