Positioning systems QSZE, QLZE, QST / KE Based on the QL and QS profiles we have developed innovative linear axes especially for use in the food and pharmaceutical industries. There are several drive options: toothed belt, trapezoidal thread spindle or ballscrew spindle, and two different guide systems are available: rail guides and roller guides. The sheet metal coating helps to save cost compared to the solid construction of linear systems. The use of stainless steel makes the systems resistant against aggressive media, i.e. cleansing agents, surfactants, solvents, etc. The existing clean-room certificates are also valid for these systems.
