No. BH-D 3 jaws (Center mounting) Technical data Actual gripping force diagram Safety advice / danger of damage: When using taller / heavier jaws and / or clamping on a bigger diameter reduce draw pull / rotating speed accordingly. The data in the diagram refers 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. Speed (r.p.m.) FG Gripping force (total on 3 jaws) (kN) ■ Large through-hole ■ 3 jaws * For internal clamping reduce the draw pull by 30%.
