	SF-1 1.Dry or only a trace of grease or oil required maintenance free. 2.Low friction and with long life. 3.Low vibration,low noise and non-pollution in operation. 4.Electroplating is possible to prevent corrosion.It is widely used in various sliding motions automobiles,agriculture machines and so on. 5.Low stick slip properties ensuring accuracy of machine operation under low sliding speeds. 6.Load will spread over a wider area due to the bearing material's elastic nature. 7.PTFE and Lead film is transferred to the mating shaft to improve running properties. 8.It can be used in low hardness of mating shaft,so the shafts processing is easy. 9.The machine will be compact because of the thin thickness and low weight of the bush.
	SF-1P 1.It is efficient even under sudden break off the lubricating oil,wear resistant,and so can keep the lubricating oil clear after long period of working. 2.It can protect the mating surface from wearing. 3.It is particularly suitable for bushes in reciprocating motion. 4.It is suitable for the machine requiring harmless to people because of lead-free. 5.It is used in shock absorber of motorcycles and various hydraulic cylinders,hydraulic motors and pneumatic elements etc.
	SF-1B 1.PTFE and lead 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.
	SF-1T 1.Low friction under oil condition. 2.Wear resistant and anti-impact. 3.At hydrodynamic lubrication,the PV limit reaches to 120N/(mm*mm)*m/s. 4.It is the best choice for the bushes in various kinds of gear pumps as well as plunger,vane pumps and so on.
	SF-1W 1.PTFE and fibre can protect the shaft while in operation. 2.It is suitable for the machine required harmless to people because of Lead-free. 3.Goodload capacity and anti-wear. 4.Bronze and steel have good thermal conductivity. 5.Anti-corrosion because of surface plating. 6.It is widely used in general machines,and suitable for food machine,pharmaceutical machine,tobacco machine etc.It will subsitute SF-1 in future because of environment protection.
	SF-1D 1.PTFE with oil fibre can protect the shaft,while machine in operation. 2.It is of low friction coefficient,anti-wear. 3.Good running in property. 4.It fits well in motion of circumrotation,sway and to-and-fro. 5.It can be used in food machine,pharmaceutical machine etc.due to lead-free. 6.Besides the same function of SF-1P,SF-1D in particular fits frequently reciprocating motion with a high side force, it is widely used in automobile,motordamper and oil pumps etc.
	SF-1S 1.PTFE with oil fibre can protect the shaft,while machine in operation. 2.It is of low friction coefficient,good anti-wear. 3.Good running in property. 4.It fits well in motion of circumrotation,sway and to-and-fro. 5.Good anti-corrosion. 6.It can be used in food machine, pharmaceutical machine etc.due to lead-free. 7.It is mainly used in the condition of strong acid and alkali, such as chemical industry, pumps,valves etc.
