Lubrication Intervals And Amounts; Lubricants - ABB ACS800 Serie Manuel D'installation

6.2.3 Lubrication intervals and
amounts
Lubrication intervals for vertical machines are half of the
values shown in the table below.
The lubrication intervals are based on a bearing operat-
ing temperature of 80°C (ambient temperature +25°).
Note! An increase in the ambient temperature raises the
temperature of the bearings correspondingly. The
values should be halved for a 15°C increase in bearing
temperature and may be doubled for a 15°C decrease
in bearing temperature.
Higher speed operation, e.g. in frequency converter
applications, or lower speed with heavy load will require
shorter lubrication intervals.
WARNING
The maximum operating temperature of the grease
and bearings, +110°C, must not be exceeded.
The designed maximum speed of the motor must
not be exceeded.

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 specifi cation 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,
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.
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 Albida EMS 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 manufac-
turer that the qualities correspond to those of the above
mentioned lubricants, or, if the compatibility of the
lubricant is uncertain, contact ABB.
