Lubrication intervals for vertical machines are half of the
above values.
The amount of grease stated in the table should be
doubled if an automatic regreasing system is used.
The table values are based on the motor running at
rated output in an ambient temperature of about +25°
(approx. 80°C bearing temperature). The values should
be halved for 15°C increase in bearing temperature and
may be doubled for 15°C decrease in ambient tempera-
ture.
Warning
The maximum operating temperature of the grease
and bearings must not be exceeded.
Higher speed operation, e.g. in frequency converter
applications, or lower speed with heavy load will require
shorter lubrication intervals. Consult ABB Sales Office
in such cases.
Suitability of bearings for high-speed operation must
also be checked.
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 70-150 cST at 40°C
- consistency NLGI grade 2 or 3
- temperature range -30°C - +140°C, continuously.
Grease with the correct properties is available from all
the major lubricant manufacturers.
The following (or similar) types of high performance
grease can be used
• Esso Unirex N2 or N3
• Shell Albida EMS 2
• SKF LGHQ 3
• Mobil Mobilith SHC 100
• Klüber Kluberplex BEM 41-132
NOTE! Always use high speed grease for high speed
machines and some other models, e.g. M2/M3_ 355
and 400 2-pole machine, when the speed factor is
higher than 400 000 (calculated as Dm x n where Dm =
average bearing diameter, mm; n = rotational speed, r/
min). 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
The following normal types 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.
Warning
Grease can cause skin irritation and eye inflamma-
tion. Follow all safety precautions specified by the
manufacturer.
Spare parts
Spare parts must be original parts supplied and
checked by ABB.
Requirements in Standard IEC 79-19 should be re-
spected.
When ordering spare parts, the full type designation and
product code, as stated on the rating plate must be
specified.
