The RÖHM key bar chucks with quick jaw change system convince in two ways. On the one hand the jaws can be quickly and easily turned, changed or offset over the entire clamping range within a few seconds. On the other the key bar chucks convince with maximum clamping forces and maximum accurancy thanks to direct force transfer via the key bar system. Large, straight surfaces transmitting the force from the key bar to the jaw teeth guarantee long life and produce a very high clamping force combined with an accurancy which is twice high as required by DIN 6386. The high clamping force is achieved without much physical effort by manually turning the key. ADVANTAGES AT A GLANCE - Maximum clamping forces thanks to direct force transfer via the key bar system - Maximum concentricity and axial run-out tolerance - High user-friendliness thanks to quick jaw change system DURO-T key bar chucks are successfully used wherever extremely high tension forces, high concentric accuracy and reliable continuous repeatability are needed. For lathes. Suitable for milling machines, dividing attachments and machining centres in connection with a base plate, non rotating. The jaws can be quickly and easily reversed, exchanged or relocated over the entire gripping range. The jaws retain their accuracy if they are always used on the same chuck and when base jaws and top jaws are kept screwed together as a matched set for recurring work. It is therefore advisable to stock several jaw sets.
