Lubrication

Relubrication Fig. 8
The spherical roller bearings used in FSDR .. K Relubricating the labyrinth between the outer seal and
housings can be relubricated via two drilled cover (one V-ring)
and tapped G 3/8 holes in the housing base
(† fig. 7). SKF recommends using an auto-
matic lubrication system like the SKF MultiLube
pumping unit († Centralized lubrication systems,
page 48).
Relubrication instructions (which form part
of the mounting instructions for the housings)
are available on request.
Relubricating the seals
FSDR .. K housings with one V-ring per side have
two drilled and tapped G 1/8 holes in the cover
on each side of the housing. Grease introduced
in either of the holes will relubricate both the
V-ring and the labyrinth seal. Choose the hole
that is most convenient († fig. 8). Fig. 9
FSDR .. K housings size 49/1320 with two Relubricating the space between two V-rings
V-rings per side have three drilled and tapped
holes in the cover on each side of the housing.
The hole that supplies grease to the space
between the two V-rings has two alternative
grease inlets (both G 3/8). Choose the one that
is most convenient († fig. 9). The single hole
(G 1/8) supplies lubricant to the labyrinth seal
(† fig. 10).
Renewal
Used grease should be replaced with fresh
grease on a regular basis, typically every two
to three years. Grease samples should be
drawn and analyzed, and the interval adjusted
accordiningly. To simplify the renewal process,
the covers and labyrinth rings are split and can
be removed without removing the cap. Fig. 10
