Speed (r.p.m.) FG Gripping force (total on 3 jaws) (kN) 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 refer to 3-jaw chucks, newly maintained according to their service manuals, using SMW-AUTOBLOK K05 grease, operated at 6 bar (87 psi). The speeds refer to a static bracket. The static and dynamic gripping forces have been measured using MHB hard top jaws placed in a position, not exceeding the outer diameter of the chuck. Actual gripping force diagram Subject to technical changes.
