SF-1T is a new kind of SF-1 which composes of a specially designed surface layer of PTFE formulations and is specifically applied for the high PV bushes of gear oilpumps.
SF-1T is to be 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/mmJ • m/s. It is a best choice for various kinds of gear pumps as well as plunger pumps, vane pumps and so on.
