Lubrication

The specified grease data apply for the data specified on the rating plate data and for high-
quality grease in accordance with the specifications in these operating instructions. These
greases significantly exceed the requirements according to DIN 51825 and ISO 6743‑9,
thereby permitting the specified relubrication intervals.
Initial lubrication
For initial lubrication of the bearings (when delivered), the lubricating grease ESSO / Unirex N
(standard version) or Lubcon / Sintono GPE702 (Performance version) is used.
Grease selection criteria
High qualityISO‑L‑X BDEA3 grease according to ISO 6743-9 and K3N‑20 grease according
to DIN 51825 with lithium soap as a thickener and an upper service temperature of at least
+140 °C / +284 °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.
