Siemens SINAMICS G115D

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 󹪝gure 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 speci󹪝ed by Siemens:

Grease service life of roller bearing greases
Roller bearings and the clearance in front are 󹪝lled with su󹪟cient grease.
Under approved operating conditions and ambient temperatures, no regreasing is required.
We recommend that the grease in the bearings is also renewed when the oil or shaft sealing
rings are replaced.
