2、Porous bronze 0.2-0.3mm
3、Steel backing 0.7-2.3mm
4、Tin-plating 0.005mm or copper plating 0.008mmCHARACTERISTIC:1.No or less lubrication is used for handing or cannot add oil ,it neet not maintain orreduce to maintain during usage.
2.Fine antifriction, small friction coefficient, 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 noises, avoid pollution, improve working condition.
6.Can form into diversion velum in the course of movement. favorable protection forgrinding bearing no grip appearance.
7.Less requirement for grinding bearing, all the bearings that not hardening and tempering could be used, accordingly reduce some difficulties about machining accessories.
8.Thin wall structure, light weight, lessen mechanical cubage.
9.The backside can, late mul-metal, can use in the corrosion medium. at present, have applied widely all sorts of mechanical arthrodia, for example, printing press, spinning machine, tobacco machine, micro-machine, automobile, motorcycle, agriculture machine.
