Table 7-2 Rolling-Contact Bearing Greases - Siemens 1PH728 Operating Instructions Manual

Maintenance
7.1 Maintenance
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 3
ARAL Aralub 4340
DEA Glissando 30
ESSO Beacon 3
FUCHS Renolit FWA 220
SHELL Alvania RL3
WINTERSHALL Wiolub LFK 3
These greases have lithium soap as the 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).
