Product overview

High-resolution high-load linear actuator. Stepper motor for high torque. Highly dynamic, closed-loop DC and BLDC motors for high velocities. Robust design for industrial environments.

High-quality components

Ground ball screw for high velocities
Low-friction output shaft bearing can handle lateral forces to 100N
Nonrotating tip for uniform motion prevents wobble, torque, and wear at the point of contact
Contactless limit switches protect the mechanics, a direction-sensing reference switch simplifies automation tasks
Optional on request and at additional charge: Increase of drive force to 1000 N.

Application fields

Research. Automation. Optical alignment.

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.
