Introduction
HIB-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=16-25 Mpa,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.it's successfully tested over one million times by changjiang hydraulic equipments company.
