Reference-class linear stage
High travel accuracy and load capacity thanks to recirculating ball bearing guides. Precision ball screw with 5 mm pitch. Stress-relieved aluminum base for high stability. Noncontact inductive limit switches.
Drive types
- Closed-loop DC servo motor with rotary encoder on the motor shaft
- 2-phase stepper motor for high torque even at low velocities and high resolution
Highly accurate position measuring with incremental linear encoder
Noncontact optical linear encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.
Recirculating ball bearing guides
When carefully assembled, recirculating ball bearing guides are distinguished by a beneficial combination of high load capacity, lifetime, maintenance-free operation, and guide accuracy. The moving part of the stages is supported by four preloaded recirculating ball bearing units, which run on two guide rails. Each bearing unit is made up of two independent rows of circulating ball bearings.
Minimum incremental motion
In conjunction with the SMC Hydra controller, versions with stepper motor and integrated linear encoder achieve repeatable minimum incremental motion in the range of the sensor resolution. The same configuration achieves constant low velocities of a few sensor increments per second.
Application fields
Sample inspection. Scanning. Research. Semiconductor technology.

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.
