Motors with regreasing nipples
Lubrication information plate and general lubrication
advice
If the machine is fitted with a lubrication information
plate, follow the given values.
On the lubrication information plate, regreasing intervals
with regard to mounting, ambient temperature and speed
of rotation can be defined.
ABB policy is to have reliability as a vital issue in
bearing lubrication intervals. That is why we follow the
L1-principle.
Manual lubrication
Regreasing while motor is running
- Remove grease outlet plug or open closing valve if
fitted.
- Be sure that the lubrication channel is open
- Press the specified amount of grease into the bearing.
- Let the motor run 1-2 hours to ensure that all
excess grease is forced out of the bearing.
Close the grease outlet plug or closing valve if fitted.
Regreasing while motor is at a standstill
Regrease motors while running. If this is not possible,
lubrication can be carried out while the machine is at a
standstill.
- In this case, use only half the quantity of grease, then
run the motor for a few minutes at full speed.
- When the motor has stopped, press the rest of the
specified amount of grease into the bearing.
- After 1-2 running hours close the grease outlet plug or
closing valve if fitted.
Automatic lubrication
The grease outlet plug must be removed permanently
with automatic lubrication or open closing valve if fitted.
Some motors may be equipped with a collector for old
grease. Follow the special instructions given for the
equipment.
We recommend only the use of electromechanical
systems. Contact your local ABB Sales Office.
The amount of grease per each lubrication interval
stated in the table should be doubled if an automatic
regreasing system is used.
If 2-pole motors are being automatically regreased, the
note (NOTE!) concerning lubricant recommendations
given for 2-pole motors in the chapter Lubricants shall be
followed.

Factors influencing the lubrication intervals
Lubrication intervals for vertical machines are half of the
above values.
The lubrication intervals are based on bearing operating
temperature 80°C (ambient temperature of about + 25°).
Note! An increase in the ambient temperature raises the
temperature of the bearings correspondingly. The values
should be halved for 15°C increase in bearing temper-
ature and may be doubled for 15°C degrease in bearing
temperature.
WARNING
The maximum operating temperature of the
grease and bearings must not be exceeded.
Lubricants
WARNING
Do not mix different types of grease.
Incompatible lubricants may cause bearing
damage.
When regreasing, use only special ball bearing grease
with the following properties:
- good quality grease with lithium complex soap and with
mineral- or PAO-oil
- base oil viscosity 100-160 cST at 40°C
- consistency NLGI grade 1.5 - 3 *)
- temperature range -30°C - +120°C, continuously.
*) For vertical mounted motors or in hot conditions a
stiffer end of scale is recommended.
