Flange self-lubricating bearing SF _1f 20115, Jiashan Rongchang sliding bearing, also known as Rongchang oil-free bushing, or Rongchang self-lubricating bearing, consists of four layers.

1.？ PTFE/Pb？ Mixture? 0.0 1~0.03mm, wear-resistant material, which can form a transfer film to protect the grinding shaft during operation.

2.？ 0.2~0.35mm copper powder layer improves the bonding strength between PTFE/Pb and steel plate, and has good bearing capacity and wear resistance. At the same time, copper is a good heat conducting material, which can quickly transfer the heat generated during the operation of the bearing.

3.？ Low carbon steel, improve bearing capacity and heat transfer.

4.？ Copper/tin electroplating layer
