XY Stages

Flat precision XY stage with 300 mm travel, 2.3 µm repeatability, 22 kg load

High loads with long travels

The KT470 XY stage with stepper motor is used in 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.

  • Positioning of loads up to 230 N with an economical drive
  • Reduction of random errors to a minimum
  • very high reliability with minimal frictional resistance by using of lapped cross roller bearings


  • Available with DC or stepper motor
  • High-resolution measuring system
  • Configuration for cleanroom, laboratory or production
  • Customized development with 3D design, prototypes, series production


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.

Fields of application

Fast scanning applications and dynamic web travel e.g. semiconductor inspection, wafer inspection, chip testing, metrology systems, automatic optical inspection (AOI), measuring instruments, metrology, inspection systems, tool measurement
