Mobil Polyrex EM is a blue in color NLGI 2 polyurea grease 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. 

Tubes contain 13.7oz (388g) each. 

Benefits: 

  • Outstanding grease life: Outstanding long-life, high-temperature lubrication of ball and roller bearings, particularly in sealed-for-life applications. 
  • Advanced polyurea thickener: Increased durability versus conventional polyurea greases when subjected to mechanical shear forces. 
  • Excellent corrosion resistance: Provides protection against rust and corrosion. Provides additional protection under mild salt-water wash conditions. 
  • Low-noise properties: Suitable for lubrication of ball bearings in many noise-sensitive applications. 

Applications: 

  • 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
