Speed (r.p.m.) FG Gripping force (total on all jaws) (kN) The data in the diagram refers to 6-jaw chucks, newly maintained according to their service manuals using the original lubricant. 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. * 2 sets (= 6 pieces) per chuck are required. **For internal clamping reduce the draw pull by 30%.
