Mounting with thread to rotor
B-12
1.
Clean the surfaces at the sealing cone [DF] and
apply mounting paste.
2.
Screw the rotary joint [1] into the roller.
3.
If the rotor version is not a standard version, use a
sealing ring or an O ring for sealing.
Mounting with K flange [2] and inner ring [3]
NOTE
Mounting with K flange and screwed flange requires a minimum distance of [MA]
≥
1 mm.
Otherwise leakage may occur at the sealing element and the rotary joint, the inner pipe
and the roller may be damaged:

for additional information.
3.
Mount K flange [2] with screws over rotor [80] and
place inner ring [3] into rotor groove
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 centered with reference to the rotary
joint and the roller [W]. If you encounter resistance,
check for correct position. Run-out and axial tension
cause malfunctions of the rotary joint.
5.
If you use a flat packing [7], 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
