Mobil Polyrex EM 14.1 oz Electric Motor Grease

Mobil Polyrex™ EM

Electric Motor Bearing Grease

Product 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.

Features and Benefits

Mobil Polyrex EM and Mobil Polyrex EM 103 offer the following features and benefits:
Features Advantages and Potential Benefits
Outstanding grease lifeOutstanding long-life, high-temperature lubrication of ball and roller bearings, particularly in sealed-for-life applications
Advanced polyurea thickenerIncreased durability versus conventional polyurea greases when subjected to mechanical shear forces
Excellent corrosion resistanceMobil 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
Low-noise propertiesMobil Polyrex EM is suitable for lubrication of ball bearings in many noise-sensitive applications

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 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. For specific questions about grease compatibility, contact your Mobil representative.

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 and Approvals

    Mobil Polyrex EM meets or exceeds the requirements of DIN 51825: (2004-06): Mobil Polyrex EM K2P-20
