Description
Super-premium Mobil Polyrex™ EM Series greases are specially formulated for electric-motor bearings
- The advanced thickener formulation and proprietary manufacturing techniques provide improved bearing performance and protection for long electric motor life.
- Outstanding grease life
- Advanced polyurea thickener
- Excellent corrosion resistance
- Low-noise properties
Applications 
- 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.
- Key applications include:
- Electric motor bearings
