Reference-class rotation stage
High-precision positioning due to low-play preloaded worm gear. Preloaded pivot bearings for high travel accuracy. Clear aperture with 35 mm Ø. Unlimited travel range in both directions of rotation. Reference switch.
Reduced outgassing especially for use in vacuum environments
Most notably, for the lubrication of the guides and the spindle a material with particularly low outgassing is used. This allows a bakeout temperature of up to 80° C. With this and other modifications of the PI V6 vacuum class, this positioner can be used up to 10-6hPa.
Higher quality for applications in high vacuum
In this case, special components suitable for high vacuum are used, such as motor, measuring system, and limit switches. In addition, the surface is made of uncoated aluminum and the spindles and guides are made of stainless steel. With this, the PI V7 vacuum class is reached, which means up to 10-7 hPa.
The highest quality for special requirements in ultrahigh vacuum
In this vacuum class, the product is optimized in all details thanks to components suitable for ultrahigh vacuum in order to reach PI V9 vacuum class up to 10-9hPa. Among other things, only selected types of plastic are used for this purpose and bakeout temperatures of 120 °C with measuring system, respectively 150 °C without measuring system are applied.
Option: Measurement of the travel accuracy and positioning accuracy
Individual measurement logs available on request for wobble, axial, and radial creep. Please specify when ordering.

At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
