Product Description
High Performance Mobil SHC 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.
Mobil SHC Polyrex 102 EM Series has demonstrated up to 40% improvement in bearing torque reduction in controlled laboratory testing*.
*) Torque reduction relates solely to the performance of Mobil SHC Polyrex 102 EM when compared to conventional (mineral) reference grease of a similar viscosity grade in a deep grove ball bearing. The technology used allows up to 40 % torque reduction compared to the reference when tested in a bearing under controlled conditions. Efficiency improvements will vary based on operating conditions and equipment.
Features and Benefits
Mobil SHC Polyrex 102 EM offers the following features and benefits:
-
Outstanding long-life, extreme high-temperature lubrication of ball and roller bearings, particularly in sealed-for-life applications up to 180 °C
-
Reduced bearing torque vs conventional based greases
-
Increased stability versus conventional polyurea greases when subjected to mechanical shear forces
-
Excellent corrosion resistance and protection against rust and corrosion
-
Low-noise properties suitable for lubrication of ball bearings in many noise-sensitive applications
-
Improved low temperature performance vs conventional based greases
Applications
Mobil SHC Polyrex 102 EM greases are recommended by major bearing and electric motor manufacturers for long-life lubrication of electric motor ball and roller bearings.
Mobil SHC 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 extreme high temperatures where low oil separation is required
-
Mobil SHC Polyrex EM for ball or roller bearings operating in noise sensitive environments
