SF Bearing Application Features   1, PTEE / Pb mixture 0.01 ~ 0.03mm, a wear-resistant material, the operation of the process of the formation of a lubricating film may protect the shaft. 2, the copper layer 0.02 ~ 0.35mm improve the bonding strength PTEE / Pb and steel, with good load capacity and wear resistance. While copper is a good thermally conductive material, you can quickly transfer heat during operation of the bearing. 3, the end of carbon steel, increase the carrying capacity of the heat transfer effect of the bearing. 4, copper / tin plating 0.002mm, the bearing has good resistance to corrosion.
