The data in the diagrams refer to 3-jaw chucks, newly maintained according to their service manuals using SMW-AUTOBLOK K67 grease. The static and dynamic gripping forces have been measured using standard soft top jaws, placed in a position not exceeding the outer diameter of the chuck. ■ Large through-hole ■ 2, 3 and 4 jaws * For internal clamping reduce the draw pull by 30%.
