Initial grease fill
If no other requirements exist, the free space
in the bearing should be completely filled with
grease and the free space in the housing
should be filled to 60% of its volume. SKF can
provide values for the grease quantities for the
relevant housing size. For additional informa-
tion contact the SKF application engineering
service. Fig. 8

Relubrication
SKND converter housings have central grease
piping connectors on both sides of the housings
to relubricate the bearing and seals († fig. 7).
As the trunnion does not fully rotate, lubricant
is provided from both sides. Lubricating the
seals provides better contaminant exclusion to
extend the service life of both the bearing and
seal.
Housings with the suffix L, the variant with
sliding bushings, have two additional relubri-
cation holes positioned at the bottom of the
housing to relubricate the sliding bushing (†
fig. 8).
