The efficient linear systems from item enable users to develop automatic solutions of the highest standards. The highly accurate linear slides can be used to connect numerous axes into complete handling and positioning systems. For example: Based on a stable profile frame, the positioning system functions as a reliable aid that can be moved by hand. The Carriages with Double-Bearing Units have End Cap and Lubricating Systems that ensure smooth, play-free guidance and low noise levels. Slide Clamps are used to hold the axes in place. As a result, the positioning system can be secured in either one or both directions. More example applications: http://www.item24.de/en/applications/examples-of-applications/dynamic-elements.html
