NOTICE
If motors are attached according to IM V3, fluid present at the output shaft
over a prolonged time may penetrate and cause damage to the motors.
Ensure that fluid cannot be present at the output shaft.

● current mineral oils
Resistant to a limited degree against
● organic solvents
● hydraulic oil
Not resistant against
● concentrated acids/lyes
It is not allwed to repaint ex-type motors of MKE series to ensure that there
will be no negative effects on surface properties (e.g., insulation resistance,
electrostatic charging).
Vibrations are sine-wave oscillations in stationary use, which vary in their ef‐
fect on the resistance of the motors depending on their intensity.
Based on DIN EN 60721-3-3 and DIN EN 60068-2-6, the following values re‐
sult for Rexroth motors:
