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 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/mm2*m/s.
It is a best choice for the bushes of various kinds
of gear pumps as well as plunger pumps, vane pumps
and so on.
