If different special lubricating greases are stated on the lubricant plate, then different criteria apply.
Note
Deviating operating conditions and characteristics
Only those greases named on the lubricant plate may be used.
If the operating conditions and characteristics differ from those mentioned, other greases may
be used only after consultation with the manufacture.
Note
Use of other greases
If greases other than those named on the lubricant plate are used, it cannot be guaranteed
that they are compatible with the complete system.
If you use greases that satisfy only the minimum requirements of DIN 51825 or ISO 6743-9,
then reduce the lubrication intervals by half or adapt them as appropriate. If in doubt, consult
the manufacturer.
Recommended greases for roller bearings
For standard applications, the following high-quality greases are recommended for roller
bearings for vertical and horizontal motor constructions due to their technical properties:

Shell
ExxonMobil
Esso
BP
Fuchs
Lubcon
Addinol
FAG
For motors of horizontal construction you can alternatively use greases with NLGI class 2.
However, this reduces the lubrication interval by 20%.
