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
- 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
- Mobil Polyrex EM for ball or roller bearings operating in noise sensitive environments
Specifications & Approvals
- DIN 51825:2004-06 – K 2 P -20
Benefits
- Outstanding long-life, high-temperature lubrication of ball and roller bearings, particularly in sealed-for-life applications
- Increased durability versus conventional polyurea greases when subjected to mechanical shear forces
- Mobil Polyrex EM and Mobil Polyrex EM 103 provide protection against rust and corrosion.Mobil Polyrex EM provides additional protection under mild salt-water wash conditions versus Polyrex EM 103
