Add your own stepper motor and controller to precisely move the ball screw and carriage smoothly at high speeds, like a head on an inkjet printer. With a repeatability of ± 0.01 mm—thinner than a strand of hair—the carriage hits the same spot every time. These positioning slides work well for automated assemblies and other applications that require fine, repeatable motion control.

The carriage rides along the inside of the rail, making these slides more compact than traditional carriages and guide rails. Made of steel with a U-shaped rail, these slides resist twisting forces that could affect their positioning. This also means they can be installed with only one end supported or with both ends overhanging. The same load rating applies no matter how the slides are oriented.

Two-axis mounting plates (sold separately) secure two slides together for motion along two axes.

Travel distance per turn, also known as screw lead, is how far the carriage moves with one rotation of the ball screw.
