Mobil Polyrex EM 103
Grease for electric motor bearings
Application Mobil Polyrex EM 103
Mobil Polyrex EM 103 greases are recommended by many major bearing and electric motor manufacturers for long-life lubrication of electric motor ball and roller bearings. Mobil Polyrex EM 103 is more specifically recommended for applications such as vertically mounted bearings or very large motors where the OEM require a stiffer grease consistency. Mobil Polyrex EM 103 greases have been shown to be compatible with a number of ExxonMobil lithium complex greases, as well as competitive mineral polyurea products intended for electric motors, in accordance with the methodology of ASTM D6185. Please consult your Mobil contact if you have further questions concerning the compatibility of the greases. Key applications include: Electric motor bearings Fan bearings Hot pump bearings Factory filled, lifetime lubricated ball bearings Ball or roller bearings, under high operating temperatures where low oil separations are required Mobil Polyrex EM 103 for ball or roller bearings in noise-sensitive environments.
