Careful maintenance of the housing in conjunction with monitoring
of the operating condition of the bearing position makes
a significant contribution towards achieving a long operating life
and reliable operation.
Carry out maintenance work regularly, basing the intervals for
the various maintenance operations on the ambient and operating
conditions.
Danger of death if maintenance operations are carried out on
WARNING
a machine that is still running.
Only carry out maintenance operations when the machine is
at a standstill. Take precautions to prevent unintentional startup
of the machine.
■
Check the alignment of the housing.
■
Retightening of the foot screws and connecting screws.
This should be carried out more frequently at first after
commissioning and at longer intervals later.
■
Inspect the housing for damage. Any indications such as
conspicuous noise or unusual grease escape must also be noted.
■
Relubrication of the seals. Taconite seals are equipped with
lubrication nipples for this purpose. If the ambient air contains
high levels of dust, the seals must be relubricated more
frequently.
■
Carry out a grease change. The housing must be opened and
the used grease replaced by new grease.
■
As an alternative to a grease change, relubrication can be carried
out. A lubrication nipple is provided in the upper housing section
for this purpose. The grease outlet hole in the lower housing
section must be open during relubrication.
■
Clean the housing to remove baked-on material and other coarse
contaminants.
The grease quantities required for relubrication of the bearing can
be calculated using the electronic product selection and advisory
system medias at http://medias.schaeffler.de.
Lubricating greases should not be mixed. The grease used for
relubrication must be the same as that used in initial lubrication.
When relubricating bearings with a circumferential lubrication
groove, the grease is introduced into the housing via the central
lubrication hole, Figure 30, page 29,
the grease acts directly on the bearing raceway.
