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

Maintenance
Notice
Observe the basic lubrication interval (see section entitled "Measures, intervals").
Notice
If the period between delivery and commissioning of the motor is long, the bearings
must be relubricated.
The grease change intervals apply for normal loads, operation at speeds that
accord to those specified on the nameplate, precision-balanced running, as good
as 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
ARAL / Aralub 4340
DEA / Glissando 30
ESSO / Beacon 3
FUCHS / Renolit FWA 220
SHELL / Alvania G 3
SHELL / Alvania R 3
WINTERSHALL / Wiolub LFK 3
These greases have Lithium soap as thickening agent and mineral oil as the basic
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
SHELL Alvania G3 grease is normally used to initially lubricate the bearings.
