Design and function
The design of the Rotoguide high-precision positioning device is based on an air bearing with micro-jet technology. The jet shape ensures maximum load capacity and tolerance against contamination. Shafts and bearing parts are machined to ultra-high precision for a positioning accuracy within μm range. A contact-less vacuum rotating union with a very low leakage rate can be integrated for vacuum applications. Thanks to the contact-less design, linear air bearings are free from wear and resilient to high loads.
