Mobil Polyrex EM 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 a stiffer grease consistency may be required by the OEM, and low noise properties are not required. Mobil Polyrex EM greases have been shown to be compatible with a number of ExxonMobil lithium complex greases, as well as competitive electric motor mineral polyurea products, as determined by the methodology of ASTM D6185.  Key applications include: Electric motor bearings; Fin fan bearings; High-temperature pump bearings; Factory-filled, sealed-for-life ball bearings; Ball or roller bearings operating at high temperatures where low oil separation is required; Polyrex EM for ball or roller bearings operating in noise sensitive environments
