Factors infl uencing 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 temperature and may be doubled for 15°C
decrease in bearing temperature.
WARNING
The maximum operating temperature of the grease
and bearings must not be exceeded.

4.1.6 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.
Grease with the correct properties is available from all
major lubricant manufacturers.
Admixtures are recommended, but a written guarantee
must be obtained from the lubricant manufacturer
especially 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
recommended in high bearing temperatures in
frame sizes 280 to 450.
If the ambient temperature is below -25°C or above
+55°C, or bearing temperature is above 110°C, consult
ABB Sales Offi ce regarding suitable grease.
The following high performance grease can be used
– Esso Unirex N2, N3 or S2 (lithium complex base)
– Mobil Mobilith SHC 100 (lithium complex base)
– Shell Albida EMS 2 (lithium complex base)
– SKF LGHQ 3 (lithium complex base)
– Klüber Klüberplex BEM 41-132
(special lithium base)
– FAG Arcanol TEMP110 (lithium complex base)
Lubrication intervals for other grease fullfi lling the
required properties, contact your local ABB Sales
Offi ce.
