Product Description
Mobil Polyrex™461 EP is a shear-stable polyurea grease with excellent extreme-pressure (EP) and load-carrying characteristics. The proprietary polyurea thickener system exhibits excellent resistance to oxidation and oil separation at operating temperatures as high as 170°C. With its outstanding high-temperature oxidation stability, load-carrying capability, shear stability, water resistance and wide operating temperature range, Mobil Polyrex™461 EP is an excellent multi-purpose grease for a wide array of industrial applications such as steel mills and wood pellet machines. This grease has excellent pumpability in central grease systems. Recommended operating temperature range is from -20 °C to 170 °C.
Mobil Polyrex™461 EP meets the claim by DIN KPF1P-20.
Features and Benefits
EXTREME-PRESSURE PROTECTION AND THERMAL STABILITY
Mobil Polyrex™461 EP contains a proprietary extreme-pressure package with solid additives that provides load-carrying capability without degrading the thermal stability of the grease at high temperatures. This grease can provide a high level of wear and extreme-pressure protection up to 170°C without rapid oxidation of the anti-wear or EP additives. Very good anti-oxidation protection imparted by the advanced polyurea thickener.
EXCELLENT PUMPABILITY IN CENTRALIZED GREASE SYSTEMS
Due to consistancy grade NLGI 1 this grease is suitable for long distribution systems with very good mobility down to 0°C. Grease can allow to stretch performance to -20°C depending on central system design.
GOOD WATER PROTECTION
Mobil Polyrex™461 EP provides an effective water resistance to keep grease in place. Corrosion prevention protects bearings in presence of water
Applications
Suitable for medium to slow speed moving plain or roller bearings exposed to high temperatures, severe load and shock loading in the following industrial applications:
Steel mill continuous casters & roll mills
Wood pellet mills
Cement, Glass, Mining, Chemical plants equipment
