Long lifetime despite dry running

This linear axis is used as a powerful component for multi-axis systems and for highly dynamic transfer systems. It enables fast positioning with extremely high resolution in ultra-high vacuum, even in the vertical direction. A ball screw ensures high stiffness and standstill stability at high speed. The system does not require liquid lubricants and still offers lifetime in the range of many kilometers.

Fields of application

High-precision transfer systems in ultra-high vacuum under extreme ultraviolet radiation, semiconductor fabrication, beam shaping for exposure processes, surface analysis and sensor positioning, mass spectrometry, OLED coating processes, layer thickness measurement and layer rate measurement, surface coating (sputtering, vapor deposition), beam exits, experimental setups, sensor arrays for investigations of samples close to their native state
