Linear Axes

Focus linear axis with 25 - 50 mm travel, 1.6 µm repeatability, 4 kg load

Integratable for horizontal and vertical applications

This compact and robust linear axis is easy to integrate and is characterized by an optimum price-­performance ratio together with precise operating parameters. For this reason, this linear axis is favored for large and small series.

  • Ideal for high precision focusing of sensors or optics
  • Perfect flatness with up to ± 0.6 µm
  • Load capacity up to 45 N


  • Available with DC motor or stepper motor
  • With linear scale for a highly accurate measurement of the actual position up to ± 0.3 µm
  • Version for clean room and vacuum on request

Fields of application

Focusing of sensors or optics, setup of scanning applications, laboratory microskopy, handling systems, printing, multi-axis systems, 3D printing, research and development

The LA85-SM can also be equipped with a linear scale in the stepper motor version.

This allows the actual position to be measured with a high accuracy of ± 0.3 µm and, for example, a measuring process to be triggered on-the-fly. Please contact us for the necessary trigger module.

However, an actual closed-loop position control with stepper motor is only possible with our FMC 2xx controllers. For such cases, a DC or BLDC drive is usually more suitable.
