8.2.9 Change the roller bearing grease
The roller bearings are lubricated in the factory with the greases listed in the table.
Renew the grease quantify for grease-lubricated bearings with each oil change.
Clean the bearing before filling it with fresh lubricant.
In the case of bearings on the output shaft or intermediate shafts, the grease quantity must
fill 2/3, and in the case of bearings on the input side, 1/3 of the space between the rolling
elements.

8.2.10 Service life of the lubricants
Note
In case of ambient conditions deviating from normal conditions, e.g. high ambient
temperatures, high relative humidity, aggressive ambient media, the intervals between
changes should be shorter. In such cases, contact Technical Support for assistance in
determining the individual lubricant change interval.
Note
Oil sump temperatures above +80 °C can reduce service life. A temperature increase
by 10 K halves the service life by the amount as shown in the figure titled "Guide values for
oil change intervals".
For a +80 °C oil sump temperature, the following service life can be expected when
observing the properties specified by Siemens AG:
Table 8- 4 Service life of the oils
Type of oil Service life
Mineral oil 10 000 operating hours or 2 years
Biodegradable oil
Physiologically safe oil according to USDA-H1/-H2
Synthetic oil
20 000 operating hours or 4 years
