Adjustable Motor-Mounting Bases
Increase energy efficiency in belt-driven systems while reducing wear on components—use one of these bases to adjust your motor position to get the proper belt tension.
Bases for constant-speed applications keep your motor in a fixed position while operating.
Bases for variable-speed applications allow movement while operating to compensate for vibration and varying loads. They’re often used for automatic belt tensioning with spring-loaded pulleys in variable-speed drive applications.

Dry-Running Positioning Slides for Stepper Motors
With PTFE sleeve bearings and a low-friction ball screw, these slides don’t require the mess and maintenance of lubrication but still give you precise positioning anywhere along the length of their stroke. Because they have sleeve bearings, they have fewer moving parts, so they perform better in dusty and wet environments than slides with ball bearings. They’re also better at handling impact and vibration.
All slides require a stepper motor, driver, and controller (not included) to operate. As part of this system, they move in precise increments, like the head on an inkjet printer. These positioning slides work well for automated assemblies and other applications that require fine, repeatable motion control.
Travel distance per turn, also known as screw lead, is how far the carriage moves with one rotation of the ball screw.

Positioning Slides for Stepper Motors
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.
