drylin® ZLW 7th axis for Universal Robots

Linear axis for robots

Toothed belt axis + adapter kit for UR + gearbox and motor + energy chains, upon request with UR cap integration

Users can now easily add a 7th axis to their existing articulated arm robots:
the new adapter kits for ZLW toothed belt axes extend the workspace or the radius of action of your robot by the so-called 7th axis. The high compatibility enables the integration not only in robolink® articulated arm robots, but also in external robots such as the Universal Robots.
