ELECTRIC MOTOR GREASE

Electric motor bearing grease Product Description Super-premium Mobil 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. Outstanding grease life Advanced polyurea thickener Excellent corrosion resistance Low-noise properties Features and Benefits 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 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. 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 Mobil Polyrex EM for ball or roller bearings operating in noise sensitive environments Technical specifications Grade NLGI 2 Thickener Type Polyurea Color, Visual Blue Copper Strip Corrosion, 24 h, 100 C, Rating, ASTM D4048 1A Corrosion Preventive Properties, Rating, ASTM D1743 PASS Dropping Point, °C, ASTM D2265 260 Four-Ball Wear Test, Scar Diameter, mm, ASTM D2266 0.41 Low Temperature Torque, Running, -29 C, g-cm, ASTM D1478 800 Low Temperature Torque, Starting, -29 C, g-cm, ASTM D1478 7500 Lubrication Life @ 177 C, h, ASTM D3336 750 Oil Separation, mass%, ASTM D1742 0.5 Penetration, 60X, 0.1 mm, ASTM D217 285 Penetration, Change from 60X to 100,000X, 0.1 mm, ASTM D217 40 SKF Emcor Rust Test, 10% Synthetic Sea Water, ASTM D6138 0.1 Viscosity @ 100 C, Base Oil, mm2/s, ASTM D445 12.2 Viscosity @ 40 C, Base Oil, mm2/s, ASTM D445 115 Viscosity Index, ASTM D2270 95 Water Washout, Loss @ 79 C, wt.%, ASTM D1264 1.9               Datasheets Product Data Sheet Safety Data Sheet
