Read MoreJLB-1B is high-quality low-carbon steel substrate, sintered porous bronze layer, the surface rolling polytetrafluoroethylene (PTFE) based wear-resistant material. Low carbon steel substrate has good mechanical properties, bronze layer improves the bonding strength between the wear-resistant materials and steel, bronze layer has good thermal conductivity, which can quickly transfer the heat generated by operations are bearing, bearing wall PTFE wear-resistant material can be used in dry friction conditions, and can remain stable for a long time, and reliable operation. The product has a low coefficient of friction, ZouGe good performance, low noise, excellent performance, and can be widely used in various mechanical sliding parts. Tin bearing surface after treatment, with better corrosion resistance.
