Lubricants
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 100-150 cST at 40°C
- consistency NLGI grade 2 or 3
- temperature range -30°C - +120°C, continuously.
Grease with the correct properties is available from all
the major lubricant manufacturers.
The following (or similar) high performance grease can
be used
•
EssoUnirex N2 or N3
•
Shell Albida EMS 2
•
SKF LGHQ 3
•
Mobil Mobilith SHC 100
•
Klüber Kluberplex BEM 41-132
•
BP Energrease LC2
The following normal type of grease can be used if the
regreasing interval is halved (these types of grease
should not be used when bearing temperature is above
100°C)
•
Esso Beacon 2 or 3
•
Shell Alvania RL2 or RL3
•
SKF LGMT 2 or 3
•
Mobil Mobilux 2
•
Kluber Centoplex 2
•
BP Energrease LS2
If the make of grease is changed and compatibility is
uncertain, consult ABB Sales Office.
Highly loaded and/or slowly rotating bearings require EP-
grease.
If the ambient temperature is below -25°C or above
+55°C, or bearing temperature is above 110°C, consult
ABB Sales Office regarding suitable grease.
NOTE!
Always use high speed grease for high speed machines
and some other models, e.g. M2/M3_ 355 and 400 2-
pole machines, where the speed factor is higher than
400 000 (calculated as Dm x n where Dm = average
bearing diameter, mm ; n = rotational speed, rpm). The
following, or similar, types of grease can be used:
•
Kluber Asonic GHY 72
•
Kluber Asonic HQ 72-102
•
Shell Albida EMS 2
•
Esso LT2
•
Mobil Mobilith SHC 100
WARNING
Grease can cause skin irritation and eye
inflammation.
Follow all safety precautions specified by the
manufacturer.
Spare parts
When ordering spare parts, the full type designation and
product code, as stated on the rating plate, must be
specified.
If the machine is stamped with a serial manufacturing
number, this should also be given.

Environmental requirements

Noise levels
Smaller machines have a sound pressure level not
exceeding 70 dB(A).
The following table shows catalogue values of sound
pressure levels at 1 m from the machines surface.
Frame Guideline sound pressure level, dB(A)
size 2 pole 4 pole
132 69 59
160 69 62
180 69 62
200 72 63

250 75 67
280 77 68

Values for specific machines can be found in the
relevant product catalogues. Tolerance ± 3 dB(A).
The table values refer to 50 Hz sinusoidal supply
conditions.
For 60 Hz sinusoidal supply, add 4 dB(A) to the above
values.
For sound pressure levels with non-sinusoidal supplies,
contact ABB Sales Office.
Sound pressure levels for all machines in the above
frame sizes having separate cooling systems and for
series M2F*/M3F*, M2L*/M3L*, and M2R*/M3R*, are
indicated in separate Machine Instructions.
Rewinding
Rewinding should always be carried out by qualified
repair shops.
Smoke venting and other special motors should not be
rewound without first contacting ABB Motors.
