greases significantly exceed the requirements according to DIN 51825 and ISO 6743‑9,
therefore permitting the specified relubrication intervals.
Initial lubrication
The following greases are used for initial lubrication of the bearings in the factory.
● Standard version: ESSO / Unirex N3
● "Performance" version: Lubcon / Sintono GPE702
Grease selection criteria
The following greases are permissible for standard applications without any special
requirements:
● High quality ISO‑L‑X BDEA3 greases according to ISO 6743-9
● K3N‑20 greases according to DIN 51825 with lithium soap as thickener and an upper
service temperature of at least +140 °C / +284 °F.
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.
