LA85-SM
Linear Axes

Focus axis (ball screw), travel 25 - 50 mm, rep ± 1.6 µm, load 4.5 kg in X/Y/Z, speed 60 mm/s

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

Options:

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.
