Max. permissible speed The maximum permissible speed has been fixed so that 1/3 of the gripping force is still available as residual gripping force if the maximum grippping is applied and the chuck is fitted with its heaviest jaws. The jaws may not project beyond the outside diameter of the chuck. The chuck must be in perfect condition. The specification DIN 6386 Part 1 shall be observed.

The specified gripping forces are standard values. They apply to chucks in a perfect condition which have been lubricated with RÖHM grease F79 and F80.
