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).
