Product Description Product DescriptionNEEDLE ROLLER BEARINGProduct Introduction:Needle roller bearings (needle bearings) is a cylindrical roller with a roller bearing, relative to its diameter, the roller both thin and long. This is called a needle roller. Despite having a smaller cross-section, has a higher load-bearing capacity, equipped with a thin and long needle-bearing roller (roller diameter D<5mm, L / D>2.5, L is the length of the roller), therefore radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial mounting dimensions restricted support structure.According to different occasions, can be used without the inner ring of the bearing or needle roller and cage assembly, when the surface of the journal bearing surface and shell holes as bearing directly match the outer rolling surface, to ensure the load capacity and operating performance and have the same ring bearing, shaft or housing bore raceway surface hardness, machining accuracy, and surface quality should be similar roller bearing rings. Such bearings can only bear radial load.APPLICATION:Needle roller bearings are widely used in cars, compressors, construction, electric motors, food industry, home appliances, etc. As a rolling element, it turns the world.Product ParametersNEEDLE ROLLER BEARING SPECIFICATIONSProduct NameNeedle Roller Thrust BearingKeywordsNeedle Roller BearingModelAXK3047-ABore Diameter Cage30 mmOutside Diameter47 mmRolling Element Diameter2 mmRaceway Dimension46 mmBasic Dynamic Load Rating, Axial16.400 NBasic Static Load Rating, Axial70.000 NFatigue Load Limit, Axial7.200 NLimiting Speed7.500 1/minReference Speed3.200 1/minWeight8.236 gOperating Temperature Min-20 CelsiusOperating Temperature Max140 CelsiusWe support customized bearings of various types, materials and usesDetailed Photos Bearing ModelBore Diameter (mm)Outer Diameter (mm)Width (mm)Weight (kg)HK31203120140.07HK33183318120.07HK33243324160.09HK36163616120.05HK36203620140.08HK37183718120.06 Main Dimensions & Performance DataModel NO.AXK3047-ADc130 mmBore diameter cageDc47 mmOutside diameterDw2 mmRolling element diameterEa46 mmRaceway dimensionEb34 mmRaceway dimensionca16.400 NBasic dynamic load rating, axialc0a70.000 NBasic static load rating, axialcua7.200 NFatigue load limit, axialnG7.500 1/minLimiting speedn?r3.200 1/minReference speed≈m8,236 gWeight Temperature RangeTmin-20 °COperating temperature min.Tmax140 °COperating temperature max.
