INTRODUCTION1,Steelbacking,sinteredporousbronze,PTFElayer 2,Small rubbing coefficient,wear-resisting and corrode resisting. 3,Long using time. 4,Reduce the cost of machine, reducing noises and negligible stick-slip. 5,It is widely used in printing machine, wearing machine, motorcycles and ect. 6,it is good environment because there are without lead. CHARACTERISTIC OF SELF LUBRICANTION BUSH Max carrying capacity 250N/mm2 Highest using temperature 280 Lowest using temperature -195 Expand cofficient 3.0*10-5/ Coefficient transmit hot 40w/mk Cofficient of wear 0.03-.23 Resist Radialization 106rads CHARACTERISTIC 1,No or less lubrication is used for handing or can not add oil, it need not maintain or reduce maintain during usage. 2,Fine antifriction, small friction coeffiction, linger operating life 3,Has measurable elastic, can distribute stress to wider interface improve bearings carrying capacity 4,coeffcient of static friction is the same to coefficient of dynamic friction, can dispel low speed creeping, ensured the working precision 5,Lessen libration, debase nises, avoid pollution, improve working condition 6,Can form into diversion velum in the course of movement ,favorable protection forgrinding bearing no grip 7,Less requirement for grinding bearing, all the bearings that not hardening and tempering could be used, accordingly reduce some difficulties about maching accessories 8,Thin wall structure, light weight, lessen mechanical cubage 9,The backside can late mul-matel, can use in the corrosion medium. At presednt, have applied widely all sorts of mechanical arthrodia, for example, printing press, spinning machine, tobacco machine, food machine, micro-machine, automobile, motorcycle, agriculture machine
