Housings for paper machines SBFN, SBPN and SDM series

Sealing solutions Fig. 6

Table 1 provides an overview of the charac-
teristics and suitability of the sealing solutions
for SKF housings for paper machines. This
information should be used as a guideline,
which cannot substitute for testing a seal in its
application.
SBFN († fig. 6) and SBPN († fig. 7) hous-
ings are equipped with labyrinth seals inte-
grated in each cover. A labyrinth ring, bolted
to the shaft, forms an axial labyrinth with the
housing cover. Shafts used with SBFN hous-
ings require machined grooves that act as oil
flingers. End covers are available for housings
mounted at the end of a shaft.
SDM housings are equipped with gap-type
seals and split oil flinger rings († fig. 8). The
seals are integrated in the covers. The flinger Fig. 7
ring is split and mounted directly onto the shaft.
The ring is positioned axially by tightening the
ring screw into a tapped hole on the shaft.
