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 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.
