ServoBelt ™ Linear Stages ServoBelt ™ Linear actuators redefine the classic belt drive, putting belts to work in an entirely new way that reduces the positioning errors and speed limitations of conventional belt drives. High Performance, Low Cost. With speeds up to 4 m/s and repeatability up to ± 4 µm per meter, ServoBelt Linear compares favorably to high-end linear motor drives costing thousands more. Limitless Scalability. With a modular chassis based on standard Bosch-Rexroth T-slot extrusions, ServoBelt Linear offers virtually limitless travel distances, making it easy to create large-format motion systems. Multiple Carriages and Axes. A single ServoBelt Linear axis will support multiple carriages with independent motion. Multi-axis configurations include Cartesian motion systems and gantry robots.

Technical Specifications Type Maximum Linear Force (lbs) Recommended | Ultimate Linear Travel Per pinion revolution time (mm) | Pitch Diameter Bearing Type Maximum Length Motor Type Accuracy (µm) Linear accuracy at stage centerline. Uni-directional Repeatability (µm) Achievable under ideal conditions. Bi-directional Repeatability (µm) Angular Deviation (±arc-sec) Yaw angle maximum in the plane of the base. Most chassis are flexible enough that this value is generally the achievable number when the unit is straightened on user surface.

The Standard carriage is more compact and uses our dual-belt drive technology. This carriage style is suitable for most applications. The LoopTrack carriage is a design in which the upper drive belt loops continuously within the carriage itself. It prevents the possibility of belt sag in inverted or cantilevered applications. Both carriages have a new “shoe” feature that doubles the pullout strength of the belt teeth compared to early ServoBelt designs. Continuous Belt ServoBelt LoopTrack supports multiple, independently moving carriages.
