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. 金屬聚合物滑動軸承，軸承結(jié)合高負載能力和與性能和自潤滑的經(jīng)濟效益潤滑金屬軸承立體剛性。軸承的結(jié)構包括一個剛性的鋼或耐腐蝕的銅襯，它提供機械強度，而具有PTFE的均勻混合物和鉛浸漬的多孔青銅燒結(jié)層間提供了低摩擦和高耐磨性。
