The specified maximum speed of rotation stated only applies when
using the maximum clamping force and the SHB-type, hard,
standard stepped jaws that go with the chuck.
The maximum permissible speed of rotation for the specific
machining has to be defined by the user on the basis of the
required clamping forces. This speed must not exceed the
maximum speed of rotation of the chuck.

24 Months
Maximum clamping cycle number

Ensure minimal weight for all jaws.
For unhardened top jaws or chuck jaws in special design, the
permissible RPM according to VDI 3106 must be calculated for the
respective machining job. Whereby the recommended maximum
speed must not be exceeded. The values calculated must be
checked by means of dynamic measurement using a clamping
force tester.
