9.1.4.1 Inspection notes for rolling-contact bearings
Inspections in the event of faults
Perform an inspection immediately in the event of faults or exceptional operating conditions
indicating an electrical or mechanical overload, e.g., overload, short circuit.
Inspecting rolling-contact bearings
When inspecting rolling-contact bearings, it is generally not necessary to dismantle the
machines. The motor only has to be dismantled if the bearings are to be replaced.
Note
Observe the regreasing intervals for the rolling-contact bearings
The regreasing intervals for rolling-contact bearings are different from the inspection
intervals. Failure to regrease the rolling-contact bearings at the specified intervals can result
in them sustaining damage.
Note
Remove spent grease before regreasing
The rolling-contact bearing's spent grease chamber only has room for a limited amount of
spent grease. When the spent grease chamber is full, the spent grease must be removed
before regreasing; otherwise it will escape into the interior of the machine. Escaping oil at the
bearing or oil escaping during regreasing is an indicator that the space for the spent grease
is full. [ID 53.01]
9.1.4.2 First service after installation or repair
Perform the following checks after approximately 500 operating hours or 1 year, whichever
comes first:
● While the motor is running, check that:
– The stated electrical characteristics are being observed
– The permissible bearing temperatures are not being exceeded
– The smooth running characteristics and machine running noise have not deteriorated
● Once the machine has been shut down, check that its foundation has no indentations or
cracks
Further checks may be required if so specified in supplementary instructions or in
accordance with the plant-specific conditions. Immediately eliminate impermissible
deviations or changes detected while carrying out checks. [ID 56.02]
