Detailed description

JLB-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.

Application Features

1. PTFE and lipophilic fiber mixture in the movement can form a good transfer film protect the shaft;
2. sintered layer and copper substrate with good thermal conductivity, can quickly transfer heat generated during the operation;
3. Copper has self-lubricating properties, can be used for long-term operation and maintenance of the site can not be shut down;
4.The copper substrate with good corrosion resistance, can be used in weak acid, alkali occasions;
5. has a good carrying capacity;
6. The iron and steel products have been widely used in metallurgical industry, high-temperature furnace steel ring parts, cement grout pumps, screw conveyors, port machinery and ship machinery fine;
7. In the external composition steel sleeve; or cuffs made to reach the hole, the effect of the end surface simultaneously.

Available forms

Straight sets, flanged bushings, WC thrust washers, skateboards and other non-standard parts and so on.
