MAINTENANCE
6.2.2. Motors with re-greasable
bearings
A. Manual lubrication
Re-greasing while the motor is running
• Be sure that the lubrication channel is open
• Inject the specified amount of grease into
the bearing.
• Let the motor run for one to two hours to
ensure that all excess grease is forced out of
the bearing
Re-greasing while the motor is at a stand still
If it is not possible to re-grease the bearings
while the motors are running, lubrication can be
carried out while the machine is at a standstill.
• In this case, use only half the quantity of grease
and then run the motor for a few minutes
at full speed.
• When the motor has stopped, apply the rest of
the specified amount of grease to the bearing.
6.2.3. Lubrication intervals
and amounts
The interval between regreasing depends a great
deal on what the motor is used for, the operating
speed of the motor, the ambient temperature
and the load type.
In the following tables, suggested lubrication
intervals are given for the most common bearing
types in operating hours, assuming an ambient
temperature of 20 °C (and bearing temperature
of approx. 70 °C). For special bearing types or
operating conditions, the lubrication interval
can be requested from ABB.

WARNING
6.2.4. Lubricants
WARNING
All open bearings are greased in the factory with
one of the following types of grease:
• SKF LGMT3
• SKF LGHP2
"LGMT3" is a lithium soap-mineral grease for
high- temperature applications. Even if high-
quality grease is used, its properties deteriorate
with time; therefore periodic regreasing is
required. It is advised to use the same factory
grease or another with equivalent properties.

THE DESIGNED MAXIMUM SPEED OF
THE MOTOR MUST NOT BE EXCEEDED.
DO NOT MIX DIFFERENT TYPES OF
GREASE. INCOMPATIBLE LUBRICANTS
