There are many typical indicators when looking for a good electric motor grease, including viscosity, consistency, thermo-oxidative resistance, antiwear, dropping point and shear stability.
Our primary recommendations for electric motor grease are Mobil Polyrex EM & EM 103* greases, which are specially designed for electric motors applications, enabling high temperature operation, long life and low noise applications.
Our secondary recommendation for electric motor grease is Mobilith SHC 100 – a high protection multipurpose grease. This is recommended particularly for electric motors exposed to harsh environments such as ambient temperatures below -20°C, or subject to a high level of vibrations or load.
Other recommendations for specific equipment builder applications include UNIREX N2 & N3 greases, which are recommend only when required to meet specific OEM approvals** (e.g., Siemens, ABB EU).
*Mobil Polyrex EM 103 grease mainly for vertical installed electric motors.
**Review EMEBS online for specific approvals.
