Applications应用
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.许多主要的电动马达，滚珠和滚子轴承长寿命润滑轴承和电动机制造商推荐的美孚宝力达EM润滑脂。
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.美孚宝力达EM 103更具体的建议，如垂直安装的轴承，还是非常大的电机的围追堵截的稠度可能需要由OEM，不需要和低噪声性能的应用程序。
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.美孚宝力达EM润滑脂已经被证明是兼容与埃克森美孚复合锂润滑脂，以及竞争力的电动马达矿物聚脲产品，如ASTM D6185的方法确定。 For specific questions about grease compatibility, contact your
Mobil representative.对于特定关于油脂的兼容性的问题，请联系您的美孚代表。
