Mobil Polyrex EM, 10/13.7 ounce tube case is a blue in color NLGI 2 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. It also has the following 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.

Application

  • 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
