SF-1B  Self Lubricating Bushing is of high safety factory, and is particularly appropriate for high temperature environment where no oil is efficient and where the machine must be under successive long period working condition. It is widely used in steel metallurgy industry such as bushed for roller grooves of successive casting machines, cement grouting pumps and screw conveyers for cement. It can also be composed in steel housing or fabricated into flanged bushed which can move both in radial and in axial directions. It can be applied in bridge bearing plate because of thicker inner surface layer to arrive 130N/mm2 　 Color Metallograph ---PTFE with lead, 0.01~0.03mm   ---Porous bronze (CuSn6.5Pb0.1),   0.2~0.3mm  ---Bronze Backing, 0.7~2.3mm

Size Specification

Application Case

1. PTFE and lead can protect the shaft while the machine in operation. 2. Bronze have good thermal conductivity, it'll divert heat while the machine operating. 3. It can be applied in the machine, working long time, which examine and repair is incapable, because the bronze can lubricate itself. 4. It is used in the feeble acid and alkali condition because of good anti-corrosion of bronze backing. 5. Good load capacity 6. It is widely used in steel metallurgy industry, such as bushed for filler grooves of successive casting machines, cement grouting pumps and screw conveyers of machine etc. 7. It can be composed in steel housing , or fabricated into flange bushes which result in function  for motion both on flange and I.D.
