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. 金属聚合物滑动轴承，轴承结合高负载能力和与性能和自润滑的经济效益润滑金属轴承立体刚性。轴承的结构包括一个刚性的钢或耐腐蚀的铜衬，它提供机械强度，而具有PTFE的均匀混合物和铅浸渍的多孔青铜烧结层间提供了低摩擦和高耐磨性。
