High Performance Electric Motor Bearing Grease

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(*).

The energy efficiency design is a trademark of Exxon Mobil Corporation.

(*) 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.

Mobil SHC Polyrex™ 102 EM | Mobil SHC Polyrex™ 103 EM

In extensive laboratory tests involving two million data points, Mobil SHC Polyrex™ 102 EM grease demonstrates reduced bearing torque up to 40% (depending on motor RPM), which can increase motor efficiency up to 0.24%.*

Proven energy efficiency benefits, which can help cut consumption and costs
Long relubrication intervals help minimize maintenance costs
Helps enhance electric motor life, which can limit replacement costs
Up to 40% improvement in bearing torque reduction

NEW Mobil SHC Polyrex™ 102 EM, scientifically proven to save energy

Consider reducing your energy consumption by switching lubrication. Introducing Mobil SHC Polyrex™102 EM, our first electric-motor bearing grease to be proven by lab tests to increase energy efficiency.

*The energy efficiency of Mobil SHC Polyrex™ 102 EM is based on its performance compared to mineral oil-based Mobil Unirex™ N2 electric motor grease. The technology used reduces ball bearing torque up to 40%, depending on motor speed and under controlled conditions. The energy efficiency claim for this product is based on reducing motor bearing frictional losses, which are typically 0.6% of motor output. Efficiency gains will vary based on operating conditions, bearing design and applications.

Features and Benefits

Mobil SHC Polyrex 102 EM and Mobil SHC Polyrex 103 EM offer 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 103 EM 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 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. 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 extreme high temperatures where low oil separation is required

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