Velocity to 50 mm/s
Preloaded, low-friction ball screw
Vacuum-compatible versions to 10-9 hPa on request

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. Versions available for vacuum environments to 10-9 hPa.

High-quality components

  • Ground ball screws for high velocities.
  • Stable bearing at shaft output reduces lateral forces on the pusher.
  • Nonrotating tip for uniform motion prevents wobble, torque, and wear at the point of contact.
  • Noncontact limit switches protect the mechanics. A direction-sensing reference point switch supports automation applications.
  • Optional on request and at additional charge: Increase of push/pull force to 1000 N.
