11.1 FNL flanged housings for bearings on adapter sleeves
da 20 - 40 mm

FNL flanged housings are well-proven
machine parts that provide simple, reliable
housing in applications without horizontal
frames. They enable the full service life potential
of the incorporated bearings to be
exploited with less need for maintenance.

Standard housing design
FNL flanged housings are non-split housings
that are produced in two designs depending
on size. Smaller sizes up to and including size
13 have a triangular flange († fig. 1), larger
sizes have a square flange († fig. 2). FNL
housings are supplied with a cover either for
shaft ends or for through shafts († fig. 3).
The housings with a cover for shaft ends have
the designation suffix A, the housings with a
cover for through shafts have the designation
suffix B.
