Lubrication - Siemens SINAMICS G115D Operating Instructions Manual

11.2.17

Lubrication

The standard version of the motors bearings are permanently lubricated (2Z bearing) and
cannot be relubricated. If this is not the case, this is indicated by a warning notice on the
motor.
The specified grease service life values are valid for an ambient temperature of up to a
maximum of +40 °C. For every 10°C increase in temperature, the grease service life is
reduced by a factor of 0.7 of the value in the table (max. +20 °C = factor 0.5).
At an ambient temperature of +25 °C, the grease service life can be expected to be doubled.
For versions with closed bearings (2Z bearings), we recommend that the bearings are
replaced after 3 to 4 years. For options with open bearings (1Z bearing: special, food, organic
grease), we recommend that the bearing grease is replaced after 3 to 4 years, regardless of
the operating hours.
