OOB-80 Bi-metallic Composite Bearings
Bemetallic Bearing with Steel Shell and Sintered Bronze cojinetes bimetálicosSteel backing lead bronze layer provides high specific loads, excellent fatigue strength under dynamic and shock load conditions, superopr performance under oscillating movement,indents or grooves in the bearing linning provide a reservoir for grease and thus allow extended re-greasing intervals. Typical application for agricultural machinery, truck suspension, lifting machinery, engine bearings etc.Steel shell backed with a lead bronze lining bearing material for oil lubricated applications. This material has high load capacity and good fatigue properties, it is widely used in automotive applications such as compressorsOOB-80 Bimetal Wrapped Bearingsetal WrappProduct Overview:Steel shell back ed with a lead bronze lining bearing material for oil lubricated applications.This marerial has high load capacity and good fatigue properties.It is widely used in automotive applications such as compreddors.Steel shell backed with a lead bronze linling beraing material for oil lubricated appli-cutions.This matrtial has high load capacitiy and good fatigue proprties.It is widely used in automotive applications such as compressors,steering gear,power steering,pedaldearings,king-pin bushes,taligte pivots,mechanical handling and lifting equpment,hydraulic motors,agricultral machinery etc.Bimetallic Bearing with Steel Shell and Sintered Bronze LiningBimetal bush is a cost saving self lubricating bearing. This type sliding bearing including engine bearing, con rod bushing, truck roller bearing, king pin bush, tractor bush, leaf spring bush, brake shoe bush, alxe bush and other type oilless bearing.The bimetallic bearing has steel shell and sintered bronze lining. Its base material is high-quality low-carbon steel. Surface of the composite bearing is sintered with low-friction copper alloy including CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30, AlSn20Cu and CuSn8Ni. As a wear-resistant layer of the bimetallic bearing, the copper alloy surface can be designed with all kinds of oil grooves, oil holes and oil pockets on basis of specific working conditions. It is perfect for use in case of difficult refueling. Materials can be provided with superb binding strength and the optimum carrying capacity by means of secondary sintering and secondary squeezing technology. OOB-80 bimetal bushing is one of standard item of our company. This type self lubricating bearing has common structure with other bimetal bearing.Structure:Low carbon steel + bronze alloy (CuPb30)Characteristics:high fatigue-resistance, high load capacity, and corrosion-resistanceApplication:OOB-80 bimetal bushing is widely used in con rod of automobile engines, transmission gearbox, construction & agriculture machinery etc1. The BIM bimetallic bearing must be designed with oil lubrication. This product is usually fully sealed and added with grease when being assembled at low speed. It is refueled with oil plug when in use.2. For instance, our product can be applied in the automobile balance bridge, spring steel seat hole, brake shoes, knuckle, movement rod, punch sliding part, and the bulldozer branch driver, etc.3. If moved at medium speed, this product should be configured with oil cup for thin oil lubrication. It is proper for use in the connecting rod, transport wheel, and the revolving shaft of the punching and shearing machine, etc.4. The bimetallic bearing is immersed in oil at high speed. For example, it can be used in the gearbox casing, oil pump, oil cylinder, engine, and the clutch, among othersTechnicalMax.LoadStatic250N/mm²Alloy HardnessHB 60-100Load140N/mm²Temp-40℃~+250℃Coefficient of friction0.05~0.12Max.SpeedMax.Speed2.5m/sThermal conductivity60W(m*k)-1Max.PVMax.PV2.8N/mm²*m/sShear strengthShear strength170N/mm²Coef.of yhermal exoansion14*10-6K-1
