Table 7-2 Rolling-Contact Bearing Greases - Siemens AH 180 Operating Instructions Manual

Maintenance
7.1 Maintenance
Notice
Observe the basic lubrication interval (see section entitled "Measures, intervals").
Notice
If there is a long interval between delivery and commissioning of the motor, the bearings
must be relubricated.
The grease change intervals apply for normal loads, operation at speeds corresponding to
those specified on the nameplate, precision-balanced running, almost neutral ambient air
and the use of high-quality rolling-contact bearing greases.
Grease types
The following high-quality rolling-contact bearing greases have been tested and are suitable:
Table 7-2
K3N-greases
ESSO / Unirex N
ARAL / Aralub 4340
DEA / Glissando 30
ESSO / Beacon 3
FUCHS / Renolit FWA 220
SHELL / Alvania RL3
SHELL / Alvania R 3
WINTERSHALL / Wiolub LFK 3
These greases have Lithium soap as thickening agent and mineral oil as the base oil. They
exceed the standard requirements of DIN 51825 in several important respects, and are
therefore compatible with the specified regreasing intervals.
Notice
Never mix greases that have different thickening agents and base oils.
Initial lubrication
ESSO Unirex N grease is used for initial lubrication of the bearings (prior to delivery).
