plain bearings,Graphite copper sleeve

metal polymer plain bearings bearings combine the high load capacity and dimensional rigidity of lubricated metallic bearings with the performance and economic benefits of self-lubrication. The structure of the bearings consists of a rigid steel or corrosion-resistant bronze backing  which provides mechanical strength, while a porous sintered bronze interlayer impregnated with a homogeneous mixture of PTFE and lead provides low friction and high wear resistance.
