L-239 High-Load Linear Actuator
Dynamic, High-Resolution Precision Drive with DC or Stepper Motor
- High drive force up to 300 N
- Travel range 52 mm (2")
- Minimum incremental motion 0.1 µm
- Velocity to 50 mm/s
- Preloaded, low-friction ball screw
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.
