PMT160-DC
Linear Stages

Precision linear stage (ball screw), travel 50 -300 mm, rep ± 1.7 µm, load 4,5 kg, speed 60 mm/s

High precision measurement stage

The PMT160 with DC motor is a precision measurement stage that has outstanding operational parameters. A preloaded ball screw ensures high stiffness and minimum backlash. The PMT160 is also available with a stepper motor.

Quick and easy to combine

The PMT160 with DC motor, in combination with a linear distance measuring system, achieves very small adjustment increments at high positioning speeds. It is easily combined to create a two axis system or, when equipped with an electromagnetic brake, is ideal for use as a vertical axis.

For high dynamic applications

The high precision linear stage is suitable for all applications that require excellent flatness, very small tolerances for pitch and yaw as well as smooth movement. The PMT160-DC is therefore primarily used in measurement engineering, micromachining or optics.
