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.

Application fields
Research, Automation, Optical alignment

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 10
