Standard housing design

Reduced grease consumption Fig. 2
Trunnion bearing housings typically require Sealing solution with one V-ring seal
large amounts of grease at frequent intervals,
to purge contaminants from the bearing and
housing. With SKF grinding mill housings
however, the highly effective multi-stage lab- Inclined outside face
yrinth seal makes it possible to extend relubri-
cation intervals, helps to eliminate overgreas-
ing and reduce grease consumption.

Easy access for inspection and maintenance
The covers and labyrinth rings are split for
easy removal. This enables the housing, bear-
ing and seals to be inspected, or replaced, and
used grease to be removed, without dis-
mounting the housing.
Machined base ends
The base ends of FSDR .. K housings are Fig. 3
machined to make alignment easier and to Machined base ends
provide a flat surface for stops († fig. 3).
Ventilating valves
Ventilating valves are supplied with the housing
(† fig. 4). They help to prevent high pres-
sures, which can be caused by heat, from
building up in the housing. The valves have a
2 µm dirt filter.
