OOB-22 Bronze Wrapped bearings with Through Holes Product Overview:The bearing are wrapped from a cold formed homogenous bronze(CuSn8)with exceptional material properties.The srandard sizes incorporate holed,which are dispersed in a special way over the whole bearing surface.The bearings are wrapped from a cold fomed homogenous bronze(CuSn8)with exceptional marerial properties.The srandard sizes incorporate holes,which are dispersed in a special way over the whole bearing surface.These holes serve as lubri-cant reservoirs to rapidly build up a lubrication film at the start of movement and thereadter reduce the running friction.The material is suitable for construction and agricultural machinery etc.where high load and slow movement occur.Bronze bushing is a kind of wrapped self lubricating bearing. Cylindrical bushing,flanged bearing and strip are available. The wrapped bronze bearing is a kind of cost-effective product, featuring thin wall, high wear resistance, and great carrying capacity. Base plate of the thin-wall bearing is CuSn8 bronze.  Allowing for different lubrication conditions, we can provide either diamond-shaped oil pockets or oil holes. The diamond-shaped oil pockets are used for grease lubrication, and the through holes are designed for fluid lubrication. In this way, oil film lubrication is guaranteed when this product starts running. It can lower the initial coefficient of friction.DescriptionOOB-22 bronze bushing is a standard item of our company. This type bronze bearing is made of specially formulated high-density bronze alloy.Material: CuSn8P0.3Characteristics:Surface can be incorporated with spherical of diamond shaped indentations or oil grooves linear. Particularly suitable for oscillating bearing.High load capacity and long lifeCheap than traditional bronze bush, cost savingAvailability:Standard cylindrical bushing is available.Special designs are produced based on your requirementCuSn6.5P0. 1 is also availableApplications:OOB-22 bronze bushing is widely used in hoisting machines, construction machines, automobiles, tractors, trucks, machine tools and some mineral engines.The wrapped bronze bearing is used as one of the truck chassis parts. Also, it can be applied in the agricultural machinery, construction machinery, cranes, conveyors, lifts, winding engines, and the levelers, among others.Technical Data:Material: CuSn8P0.3 (DIN ISO 4382-2:1991)materialCuSnPCuSn8P0.391.38.50.3Physical and Mechanical Properties ValueUnitDensity8.9gcm3Operating Temperature-80~ 200°CHardness90-120HBLoad capacity75N/mm2Maximum Speed2.5m/sOther Details:Quality Standard: DIN 1494Package: Standard export packageStandard Lead time: 30 daysShipping mode: Courier, air plane or shipSupply Ability: 500000000PCS/MonthPort of Loading: ShanghaiCertificate: ISO 9001:2008HS Code: 8483300090Advantage:Well experienced OEM manufacturer 15 years in the self lubricating bearing industry90% products export to foreign countriesTechnicalNax.LoadStatic120N/mm²Elongation40%Dynamic40N/mm²Temp-100℃~ 200℃Coefficient of friction0.08~0.25Max.Speed(Lubrication)Max.Speed2.5m/sThermalconduvtivity58W(m*k)-1Max.PVMax.PV2.8N/mm²*m/sCoef. of thermalexpansion18.5*10-6K-1Tensile strengthTensile strength450N/mm²
