QX block is a two-sided active, flexible operating magnetic clamping block. Each side has two/four 70mm QX Poles - equipped with a total 15.6/31.2kN resilience. It can be used to secure workpieces flexibly or as an additive in order to avoid tightening element, especially at high clamping vibrations. The standard height of 100,2mm can be reduced by 6mm. Likewise, both sides with standard pole extensions can be fixed or mobile provided. There are heights between 94mm and 240mm realized. The QX block is driven by a ST 211 Feme or by almost any standard 400V pole-reversal device. With distribution boxes, several QX Blocks can be driven simultaneously.
