General
Lubrication
Immediately after start-up of a newly installed
machine or of a machine which has been
standing for a long period, new grease must be
pressed into the bearings. Follow the lubricat-
ing instructions on the rating plate. The bearing
temperature increases initially because there is
a surplus of grease in the bearing housing. After
the surplus grease has run out of the bearing
housing, the temperature should reach normal
DMI machines should be lubricated with a
grease gun while the machine is running.
Lubrication
during start-up
running values (< 80°C at ambient 20°C) again.
Normally this takes a few hours.
If the machine is lubricated while standing
still, the old grease does not pass out through
the discharge opening. Instead it squeezes
between the seal ring and the shaft into the
machine and may cause serious contamination.
Use only high quality grease equivalent to ABB
grease.
Use a manual grease gun and lubricate while
the machine is running with the amount and
within the intervals specified on the rating plate.
Use only high quality grease.
Lubrication
during
operation
ABB grease is equivalent to Shell Albida EMS2
with the basic data below:
NLGI-class: 2*
Soap thickener ........lithium complex
Lubrication oil ..........Synthetic polyalphaolefin
Viscosity at 40
o
C .....100-200mm
2
/s
No EP/AW-additives with harmful effects on
bearings with polyamide or brass holder are
allowed.
*) Vertical machines are recommended to use
NLGI-class 3 if the pumpability properties of the
grease allow it.
Caution
Clean the grease nipples prior to lubrication to
prevent any impurities from being pressed into
the bearings.
Remark
Lubricate only when the machine is running, pref-
erably over 300 r/min.
Remark
Lubrication intervals and amount of grease
are listed on the rating plate.
