Possible Application

Automotive: Used in hydrodynamic or boundary lubricating condition of medium or high pressure gear oil pumps such as P=16-25Mpa, V= 3.5-5m/s. It shows the benefit of low friction coefficient, wear resistant and anti-impact properties. At hydrodynamic lubrication, the PV limit reaches to 120N/mm m/s. It is a best choicefor various kinds of gear pumps as well as plunger pumps, vane pumps and so on.   Industrial: Compressors: scroll and reciprocating; pneumatic and hydraulic cylinders, high performance pumps: axial pistons, radial pistons, gears, vanes, etc.
