6.2 Basic Principles
The procedure for determining the clamping force and speed is given in Röhm
Norm RN 1391.
The Röhm Norm 1391 can be downloaded at www.roehm.biz or can be ob-
tained free of charge from RÖHM GmbH.
The actual clamping force must be checked regularly. See Checking the
Device for Correct Operation [

The following values apply specifically to the power chuck DURO-A RC and
are required for calculation in accordance with the Röhm Norm 1391:

Centrifugal force M
cGB
per base jaw [mkg]
0.0151 0.0306 0.0637 0.1158 0.1628
The values in the table apply per jaw, i.e. the individual value must be
multiplied by the number of jaws in the chuck.
