【INTRODUCTION】IRIS-888 calcium sulfonate complex grease is modulated of high-viscosity mineral oil thickened by new thickener and added with additive as high-temperature antioxidant material. It is high performance grease with the quality of high temperature resistance, great extream pressure, excellent water resistance. Working temperature: -20～180℃。
【APPLICATION】IRIS-888 is applicable to hot/cold roller bearings of the metallurgical industry, steel roller bearings, mining machinery, large motors, heat pumps and lubricated of friction parts in other high temperature, heavy duty machine.
【CHARACTERISTICS】
1. Excellent EP&AW properties, meet the bearing lubrication of high load machinery and equipment.
2. Excellent high temperature performance, effectively extending the service life of bearings at high temperatures.
3. Excellent adhesion properties, good anti-erosion, anti-corrosion.
4. Superior water resistance, and no significant change in consistency when contact with plenty of water
5. Great thermal stability, restore the original structure when cooled to the suitable temperature.
