1.
Clean sealing surfaces DF, apply mounting paste
and place the sealing element [6] into roller [W].
2.
The flat packing a standard sealing element can also
be designed with a different element, e.g. O ring.

for additional information.
3.
Screw flange [4] to rotor [90]. Make sure that dimen-
sion [MA] is obtained after mounting of rotor [90] to
roller [W]. MA
≥
1 mm. Otherwise leakage will occur
at the sealing element and the rotary joint, the inner
pipe or roller [W] will be damaged Mount stud bolts
[9].
4.
Lift the rotary joint and insert it into the centering unit
of the roller [W].
Versions with inner pipe: the inner pipe must be cen-
tered with reference to the rotary joint and the roller
[W]. If you encounter resistance, check for correct
position. Run-out and axial tension cause malfunc-
tions of the rotary joint.
5.
If you use a flat packing, the rotary joint must be
aligned (refer to "Aligning the rotary joint in case of
sealing with flat packing").
6.
Assure the minimum distance [MA] - otherwise
leakage will occur at the sealing element and the ro-
tary joint and the inner pipe will be damaged:
MA
≥
1 mm
