Self Lubricating SF-1T Metal Gear Pump Bearing Bronze Bushings

Product Description:

SF-1T is composed of a specially designed surface layer of PTFE formulations and is specifically applied for the high PV bushes of gear oil pumps. It is to be used in hydrodynamic or boundary lubricating conditions of medium or high-pressure gear oil pumps such as P=16-25 Mpa, V=3.5-5m/s. it shows the benefits of low friction coefficient, wear resistance, and anti-impact properties. At hydrodynamic lubrication, the PV limit reaches 120N/mm'.m/s.It is the best choice for the bushes of various kinds of gear pumps as well as plunger pumps, vane pumps, and so on.
