SF-1B Bronze Pb-free self-lubricating bearing used bronze alloy as base with special formulation, sintered porous bronze as its interlayer and the Compound of PTFE and lipophilicity fiber as its surface. It offers the property of good self-lubricating, low wear, low friction, corrosion resistence. It has been widely applied to metallurgy steel machinery, joined casting machinery, cement grout pump and spiral conveyer machinery etc.

1.PTFE with Fiber 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Bronze backing 0.7~2.3mm
1. PTFE and Friber can protect the shaft, while the machine in operation.
2. It can be composed in steel housing, or fabricated into flanged bushes which result in function for montion both on flange and I.D.
3. It is widely used in steel metallurgy industry, such as bushes for foller grooves of successive casting machines, cement grouting pumps and scrow conveyers of machine .
4. Bronze have good thermal conductivity, it'll divert heat while the machine operating.
5. It can be applied in the machine, working long time, which examine and repair is incapable, because the bronze can lubricate itself.
6. It is used in the feeble acid and alkali condition because of good anti-corrosion of bronze backing.
7. Good load capacity.
