6.2.4 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 - +140°C, continuously.
*) For vertical mounted motors or in hot conditions a stiffer
end of scale is recommended.
The above mentioned grease specification is valid if the
ambient temperature is above -30°C or below +55°C, and
the bearing temperature is below 110°C; otherwise
consult ABB regarding suitable grease.
Grease with the correct properties is available from all the
major lubricant manufacturers.
Admixtures are recommended, but a written guarantee
must be obtained from the lubricant manufacturer, espe-
cially concerning EP admixtures, that admixtures do not
damage bearings or the properties of lubricants at the
operating temperature range.
WARNING
Lubricants containing EP admixtures are not recom-
mended in high bearing temperatures in frame sizes
280 to 450.
The following high performance greases can be used:
– Esso Unirex N2, N3 or S2 (lithium complex base)
– Mobil Mobilith SHC 100 (lithium complex base)
– Shell Gadus S5 V 100 2 (lithium complex base)
– Klüber Klüberplex BEM 41-132 (special lithium base)
– FAG Arcanol TEMP110 (lithium complex base)
NOTE!
Always use high speed grease for high speed 2-pole
machines where the speed factor is higher than
480,000 (calculated as Dm x n where Dm = average
bearing diameter, mm; n = rotational speed, r/min).
The following greases can be used for high speed cast
iron motors but not mixed with lithium complex greases:
– Klüber Klüber quiet BQH 72-102 (polyurea base)
– Lubcon Turmogrease PU703 (polyurea base)
If other lubricants are used, check with the manufacturer
that the qualities correspond to those of the above men-
tioned lubricants, or, if the compatibility of the lubricant is
uncertain, contact ABB.
