| Materials |
| SF-1 | SF-1 is a kind of oilless Slide Bushing made of the polytetrafluroethylene(PTEE) composite material,Which is a copper-plated steel plate on to which a porous layer of tin bronze powder is sintered and also a mixture of PTFE and lead are filled into and covered the porous layer by a roling process. |
| SF-2 | SF-2 is a boundary lubricating bushes made of the POM composite material, which also has a copper-plated steel plate on to which a tin bronze powder is sintered, modified polyformadehyde resin(POM) is firmly anchored in the sintered bronze layer. The surface of covering layer has many pockets to retain lubricating grease. |
