Direction of the axes and torques for rotation stages

RS-40 rotation stage, dimensions in mm. Note that a comma is used in the drawings instead of a decimal point.

Standard-class rotation stage

Worm drive. Aperture with 20 mm Ø. 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.

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.

Drive

Stepper motor with gearhead.

Application fields

Vacuum chambers. Research. Beamline instrumentation. Microscopy. Electronics assembly and inspection.

Note on cable length: Fixed cable, firmly attached to the product

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.
