Trunnion bearing housings for grinding mills

Lubrication Fig. 7

FSDR .. K housings are intended for grease
lubrication. The lubricant should be selected
based on the operating conditions of the bear-
ings. For additional information about lubri-
cant selection, refer to the product informa-
tion available online at skf.com/bearings.

Initial grease fill
If no other requirements exist, the free space
in the bearing as well as the gaps of the laby-
rinth seals should be completely filled with
grease. The seal counterfaces should be thor-
oughly greased. No extra grease is required
for the housing.
During start up, additional grease (typically
20 to 60 kg, depending on bearing size) should
be added to the bearing over a 30-minute
period via the annular groove and relubrica-
tion holes in the bearing outer ring.
Detailed information about the initial grease
fill is provided in the mounting instructions,
which are available on request.
