Mobil SHC Polyrex 102 EM
Mobil SHC Polyrex 102 EM is a high-performance synthetic polyurea grease specifically formulated for electric motor bearings. The advanced thickener formulation and proprietary manufacturing techniques provide improved bearing performance and long electric motor life. The grease is designed to reduce bearing torque and improve energy efficiency while maintaining reliable lubrication under demanding operating conditions.
One of the key advantages of Mobil SHC Polyrex 102 EM is its outstanding long-life lubrication capability. The grease is designed to provide extreme high-temperature performance in ball and roller bearings, particularly in sealed-for-life applications. It can operate at temperatures up to approximately 180°C, helping extend bearing life and reduce maintenance requirements.
Mobil SHC Polyrex 102 EM also offers reduced bearing torque compared with conventional greases. This can contribute to improved energy efficiency and smoother operation. The formulation provides increased stability when subjected to mechanical shear forces, helping maintain grease consistency and lubrication performance over extended service intervals.
Another important benefit is its excellent corrosion protection and low-noise characteristics. The grease helps protect bearings from rust and corrosion and is suitable for noise-sensitive applications. It also provides improved low-temperature performance compared with conventional greases, supporting reliable start-up and operation in varying ambient conditions.
Mobil SHC Polyrex 102 EM is recommended for electric motor bearings, fin fan bearings, high-temperature pump bearings and factory-filled sealed-for-life ball bearings. It is suitable for ball or roller bearings operating at extreme temperatures where low oil separation is required and for applications requiring low noise lubrication performance.
Physical characteristics include NLGI 2 consistency with a polyurea thickener and base oil viscosity of approximately 85 mm²/s at 40°C and 10.9 mm²/s at 100°C. Mobil SHC Polyrex 102 EM has a dropping point of approximately 253°C and provides low-temperature torque performance and excellent shear stability, supporting reliable long-term electric motor bearing lubrication.
