Product Description

Dry sleeve bushing oilless bearing manufacture SF-1T


SF-1T bushing is specialy designed for gear pumps.It is made on the basis of SF-1X, suits for working condition of high PV value of gear pump.It has good performance of anti-fatigue and anti-punching. 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.
