3 SF-1 Self-Lubricating Bushings SF-1 Self-Lubricating bushing: Its known as DU bushing abroad, use low carbon steel as backing, sintered bronze as it s interlayer and PTFE material as it s antiwear surface. It May be used where no oil can be applied or oil is difficult to be applied. have advantage of low wear, low friction and with long lifetime. Load will spread over a wider area due to the bearing material s elastic nature. Layer 1: PTFE with Lead (Pb) Layer 2: Porous sintered bronze Layer 3: Steel Backing Layer 4: Tin Plating or Copper Plating Low stick slip properties ensuring accuracy of machine operation under low sliding speeds. Low vibration, low noise and non-pollution in operation of working. PTFE and lead film is transferred to the mating shaft to improve running properties. It can be used in low hardness of mating shaft, so the shafts processing is more easy to do. The Machine will be compact because of the thin thickness and low weight of bushing. Note: Various backing materials are suitable for SF-1 (DU) series products according to different working conditions, such as bronze backing (SF-1B), Stainless Steel backing (SF-1S) and Lead-Free material. Electric plating is possible to prevent rusted and corrosion. it s widely used in various sliding motions of different kind of machines such as textile machine, tobacco machines, hydraulic vehicles automobiles, agriculture machine and so on. 2

We recommended design lower PV value will lead to longer service lifetime. Also do not exceed the max value of material load, speed, temperature and as much lower as possible. Note: DALON also could offer series of SF-1 (DU) bushing,such as: * SF-1T Gear Oil Pump Bushing * SF-1P Reciprocating Motion Bushing * SF-1B Bronze Based Bushing * SF-1S Stainless Steel Self Lubricating Bushing Contact us to know more detailed technical data and suitable usage. 3

The inner surface of bushing is made of self-lubricating PTFE, the outer surface steel backing, the friction coefficient of steel to steel is bigger than steel to plastic, so we should choose the light graded tight fit, prevent the axle sleeve from moving the base when working, and also preventing the inner holes from getting deformed and too big because of the large tight fit of the outer diameter. Note: Bearing Size besides above mentioned sizes, can be customized and produced according to customer s detailed dimensions (drawing or samples). 6

10 SF-2 Marginal Lubrication Bearings SF-2 Marginal Lubrication Bushing: Layer 1: POM with Lead (Pb) Layer 2: Porous sintered bronze Layer 3: Steel Backing Layer 4: Copper Plating SF-2 is triple-layer self lubricating material that can fill modified POM plastic as surface layer. it s benignant boundary lubrication material, therefore it is particularly applicable high load low-speed rotating and wing movement, as well as in the condition that frequent loaded start-stop is the requirement while hydrodynamic lubrication membrane is difficult to form, in the parts such as bearing, thrust washer, sliding block, ball socket and so on. SF-2 can take full advantage of less grease to work long time without lubrication maintenance under boundary lubrication condition. But under oil-free condition, SF-2 the frictional behavior and permissible PV value is relatively low. So general storage pit can be formed on the plastic surface, where lithium based lubricant grease or silicone grease and so on should be applied when being installed. Note: Various backing materials are suitable for SF-2 (DX) series products according to different working conditions, such as bronze backing (SF-2B), Stainless Steel backing (SF-2S) and Lead-Free material(sf-2y). 9

17 Engineering Plastic Polymer Plain Bearings Engineering Plastic Polymer Plain Bearings: EP-G series material is a thermal mould character plastic processed by crystal engineering plastic as basic material with proper intensifier and lubricant. The rigidity and high temperature engineer capability is greatly improved. Because of the use of intensifier, at the same time, the coefficient of thermal expansion, moulding shrinking rate and wriggle capability decreases consequently. The size stability is improved and EP series material range is enlarged and keeps the intrinsic antiwear capability and anti-drug capability. Base Polymers with fibers and solid Lubricants. *Magnified 200 times, dyed EP bearing cover an extremely wide range of different requirements. Typical applications include medium to high loads, medium sliding speeds and medium temperatures. It s widely used in areas of Agricultural machines; Construction machinery ; Machine building; Sports and leisure, Automotive etc. Note: The High performance polymers of the Engineering plastic bearing are composed of : Base polymer / Solid lubricants / Fibers and filling materials. Different composition rate used for different usage purpose. More details please sent enquiry. 16

26 Sintered Bronze Bushing Sintered Bronze Bearings: Sintered Bronze bushing made by bronze powder mold pressed under high pressure and then sintered under high temperature. and oil is soaked into the homogeneously spread tiny pores of the metal under vacuum. Sintered bronze bushing can withstand dry condition in medium speed and low load for sometime. More over it is cheap and stable in dimension. By increasing the porosity of DALON sintered bronze self-lubricating bearings, oil containing rate can be improved; it is long life because of high oil content and abolition the oil filling felt, therefore, the total production cost reduced. > Sintered bronze sliding bearing - oil-soaked self lubricating - pre-finished Maintenance Free >DIN1494 ; DIN1850. ISO2795 as well as beyond this standard >All special designs are produced at short period >Also Deliverable as sintered iron > Cylindrical bushings, flanged bushings, special shapes, blanks and plates are standard fabrication. With the boundary lubrication characteristics of sintered bronze bushings, this kind of impregnated oil can take the partial high contact pressure and harsh alternating shear, forming the strong adsorption oil film on the contact surface regularly and small shear strength. Meanwhile, the oil subjected to thermal shock conditions, it is difficult or cannot to occur the thermal damage (oxidation, decomposition and overlap), with high thermal stability also. This is widely used in domestic electric and electronic machines, electric tools, textile machines, chemical engineering machines, automobiles and official machines.
