Product Overview
LA series precision linear actuator with ball screw. Positioning accuracy better than 2 microns. Repeatability plus minus 0.1 micron per 1mm stroke. Max thrust force 49N. Resolution 0.0174 micron. Stroke 10mm and 30mm. DC servo motor or stepper motor. Ideal for measuring instruments optical equipment and semiconductor manufacturing.
The LA is a fully integrated rotary actuator combining servo motor, harmonic gear reducer, encoders, servo electronics, and compact mechanical packaging in a single assembly.
Precision Linear Motion
Harmonic Drive linear actuators use precision ball screw mechanisms to convert rotary servo motor output into controlled linear motion. High resolution, low lost motion, and compact form factors make them suited for precision instrumentation and automation applications.
Sub-micron Resolution
Precision ball screw delivers high linear resolution for demanding measurement and positioning.
High Accuracy
Positioning accuracy to sub-4-micron level depending on model selection.
Low Lost Motion
Minimal backlash and low lost motion for precise bidirectional positioning.
Self-Locking Option
High thrust LBC series provides self-locking to maintain position without servo power.
Servo Motor Drive
DC servo or stepper motor variants available for flexible system integration.
Compact Design
Compact actuator housings suited for integration in precision instruments and machines.
Typical Applications
The LA suits measuring instruments, test and inspection systems, optical equipment, semiconductor manufacturing, LCD manufacturing, precision laboratory automation, and industrial clamping and pressing applications.
