Mounting with 2-part clamping ring (D.R.M.B.)
The distributor ring can be clamped onto a rigid collar on the
machine (at least 8 mm wide) using a two-piece clamping ring. The
distributor ring is clamped onto this collar using two screws. The
height of the clamping ring is configured as described in the
previous chapter (

7.2.1, Page 37) .
During assembly, this two-piece clamping ring is first screwed to
the threads of the distributor ring. Once this is done, the entire
assembly group is clamped onto the rigid collar of the machine.
When mounting the chuck with a bayonet or Camlock, the
clamping ring should have a cut-out to allow access to the collar
nuts or clamping cams using the corresponding wrench.
CAUTION
The distributor ring must be aligned with the outer chuck
diameter in such a way that a radial and axial run-out tolerance
of at least 0.1 mm is achieved.
