•
Verify that the lubrication channel is open, if equipped with a handle, open it.
•
Press the specified amount and type of grease into the bearing.
•
Let the machine run 1-2 hours in order to ensure that all excess grease is
forced out of the bearing. The bearing temperature may temporarily increase
during this time.
•
If equipped with a handle, close it.
NOTE: Beware of all rotating parts during the re-greasing.
Manual re-greasing while the machine is at a standstill
Preferably, re-grease the machine while it is running. If this is not possible, or
considered dangerous, the re-greasing has to be carried out while the machine is at
a standstill. In this case:
•
Verify that the grease to be used is suitable.
•
Stop the machine.
•
Clean the grease nipples and the area around them.
•
Verify that the lubrication channel is open, if equipped with a handle, open it.
•
Press only half the amount of the specified type of grease into the bearing.
•
Run the machine for a few minutes at full speed.
•
Stop the machine.
•
After the machine has stopped, press the specified amount of the correct
grease into the bearing.
•
Let the machine run 1-2 hours in order to ensure that all excess grease is
forced out of the bearing. The bearing temperature may temporarily increase
during this time
•
If equipped with a handle, close it.
Automatic re-greasing
A variety of automatic re-lubrication systems is available on the market. However,
ABB recommends only the use of electromechanical re-lubrication systems. The
quality of the grease entering the bearing has to be checked at least once per year:
the grease has to look and feel like new grease. Any separation of the base oil
from the soap is not acceptable.
NOTE: If an automatic re-greasing system is used, double the amount of grease
indicated on the bearing plate.
7.5.4 Bearing plate
All machines with re-lubrication option are supplied with bearing plates attached
to the machine frame. The bearing plates provide bearing information, such as:
•
Bearing type.
•
Lubricant used.
•
Re-greasing interval.
•
Re-greasing amount.
