XY Stages

XY Stage with stepper motor for the inspection of surfaces and large travel distances.

High loads with long travels

The KT470 XY stage with stepper motor is used in metrology and surface inspection. Low run-off with regard to straightness and flatness can be achieved by using cross rollers. This leads to an above-average repeatability, which is the basis for good compensation. This enables an extremely high accuracy for measuring applications.


  • very high resolution up to 0.625 µm
  • Positioning of loads up to 230 N with an economical drive
  • high speeds up to 40 mm/s
  • Reduction of random errors to a minimum
  • very high reliability with minimal frictional resistance
    the use of lapped cross roller bearings


Cost-optimized and reliable positioning

Depending on customer requirements, the XY system is equipped with a stepper motor or DC motor. The DC motor is the first choice for applications with high speeds and low torques. If, on the other hand, the positioning task requires low power and low speeds, the stepper motor is the appropriate variant. The recommended load in the precision cycle is 10 kg, the maximum load is 30 kg.
