With assembly none of the pull-off threads of the internal ring may be congruent with the
slot of the external ring.
Dirty or used clamping sets have to be disassembled and cleaned before assembly.
Afterwards apply thin fluid oil lightly (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).
1. Please inspect shaft and hub fit for the tolerance specified (h8/H8).
2. Clean the contact surfaces of the clamping set and of shaft and hub and afterwards apply thin fluid oil lightly
(see illustration 4) (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).
Illustration 4: Cleaning the contact surfaces
!
Oils and greases with molybdenum disulphide or high-pressure additives, additives of
Teflon and silicone as well as internal lubricants reducing the coefficient of friction
significantly must not be used. When mounting the tapers of the clamping set free from oil
the tabular and calculated parameters deviate.
