If different special lubricating greases are stated on the lubricant plate, then different criteria apply.
CAUTION
Other ambient temperatures and operating conditions
For other ambient temperatures and operating conditions, an alternative grease to the one
stated on the lubricant plate may only be used after prior consultation with the manufacturer.
Otherwise the roller bearing could be damaged.
CAUTION
Use of other greases
If other greases are used, there can be no guarantee of compatibility with the overall system.
Otherwise the roller bearing could be damaged.
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 accordingly. 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 types of construction due to their technical properties:

Manufacturer
ExxonMobil
Esso
Fuchs
Lubcon
FAG
For motors with a horizontal type of construction, you can alternatively use greases with NLGI
Class 2. However, this reduces the lubrication interval by 20 %.
