RBC-1T gear pump bearings

Introduction

It composes of a specially designed surface layer of PTFE formulations and is specifically applied for the high PV value of gear pump bearing. It can work on the condition of semi-dry. It's used in medium, high-pressure gear pump, ram pump, vane pumps etc. As it is without lead, which make the bearing lubricating condition cleaner, and in accordance with environmental request.

Metallurgical structure

1.PTFE 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
4.Tin-plating 0.005mm or copper plating 0.008mm

Typical Application

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.
