service temperature of at least +130° C / +266° F are permissible for standard applications
without special requirements.
When selecting the lubricating grease, ensure that the technical data of the grease is suitable
for the application.
The lubricating grease must satisfy the criteria listed in the table below and must match the
operating conditions. If different special lubricating greases are stated on the lubricant plate,
then different criteria apply.
