Mobil Polyrex EM 103

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.

Formulated for electric-motor bearings, Mobil Polyrex EM 103 grease is particularly recommended by ExxonMobil for applications such as vertically mounted bearings or very large motors for which a stiffer grease consistency may be required by the OEM, and low noise properties are not required.

Mobil Polyrex EM 103 grease has earned an exceptional reputation for outstanding performance. Many major bearing and electric-motor manufacturers recommend it for long-life lubrication of electric-motor ball and roller bearings.

  • 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
  • Mobil Polyrex EM is suitable for lubrication of ball bearings in many noise-sensitive 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, and low noise properties are not required. 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.

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
  • Polyrex EM for ball or roller bearings operating in noise sensitive environments
