high quality bronze split hinged bushing,bearing bush,DU-b bushing

 

SF-1

Carbon Steel Self-lubricating

 

Material Features

 

SF-1 carbon steel self-lubrecating bearing used high quality low-carbon steel plate as base,sintered porous bronze as its interlayer and the conpound of PTFE and lead as its surface.ti offers the property of good self-lubrication,low wear,low friction good sliding characteristics,low noise.

 

SF-1W is a new type bushing without lead composition which is developed aiming at increasing demands on environmental protection.Besides its wide application on general machines,SF-1 is particularly suitable for food machine,Pharmaceutical machine,tobacco,machine etc.

 

SF-1B is of high safety factory, and is particularly approprite for high temperature environment where no oil is effcient and where the machine must be under successive long peroiod working condition. This is widely used in steel metallurgy industry such as bushes for roller grooves of successive casting machines.cement grouting pumps and screw converyers for cement.it can also be conposed in steel housing or fabricated into Flanged bushies 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.

 

SF-1T is composed of a specially designed surface layer of PTFE for mulations and is specifically applied for the high PV bushes of gear oil pumps. IT is to be used in hydrodynamic or boundary lubricating condition of medium or high pressure gear oil pumps such as P=16-25Mpa,V=3.5-5m/s,it shows the benefit of low friction coefficient,wear resistant and anti-impact properties.At hydrodynamic lubrication.The PV limit reaches to 120N/mm²·m/s.It is a best choice for the bushes of various kinds of gear pumps as well as plunger pumps,vane pumps and so on.

 

SF-1P is developed according to reciprocating motion of shock absorber and high pressure in flank,It can offer low friction coefficient and good anti-abrasion,be used in semi-dry condition.The product is applied to shock absorber of automobiles,motorcycles and pneumatic.

 

Besides it have the advantages of SF-1P,SF-1D is suitable for the places of big sides force of frequently reciprocate,The function is similar as DP4 in foreign country.Now it has replace the SF-1P step by step.

 

SF-1S is of oil resistant,acid resistant,alkaliresistant and seawater resistant,more over,there is no lead in the PTFE surface layer and so is particularly fit for bushings in food stuff machines,alkali flow meters,pumps motion elements in pharmaceutical machines,pringting machines chemical engineering machines and other ocean industry.This is a triple layers composites bushi,th base material being abronze plate and a film of heat resistant power filled PTFE being calendered onto the sintered spherical bronze interlayer.

Application Features

 

1.Working under oilless or minim oil state,maintenance free or just need a litter maintenance.

 

2.Resis Abrasion,low coefficient of friction long operation life.

 

3.Operation in -195°C~+280°C.

 

4.Good mending,low-noise,non-pollution.

 

5.Thin-walled structure,light in weight,which can reduce the machine to small size.

 

6.Forming a transferred film during operation to protece,shafe and trouble free.

 

7.Low demand to the shafe even no surface hardness treatment,which lower the cost of the mating components.

 

8.No absorption to water/oil ,small coefficient of thermal emption,good thermal conductivity and size stability.

 

9.The back of the steel strip can be plated with various metals,anti-corrosion
