Product DescriptionProduct DescriptionNeedle roller bearings are a specialized type of rolling-element bearing renowned for their unique design, which features long, thin cylindrical rollers—resembling needles—that are significantly longer than their diameter. This distinctive structure sets them apart from other bearing types, enabling them to deliver exceptional performance in applications where space is limited and high load-carrying capacity is essential.One of the key advantages of needle roller bearings lies in their high load capacity relative to their compact size. The elongated rollers distribute weight evenly across a larger contact area with the raceways, allowing them to withstand both radial and, in some designs, axial loads efficiently. This makes them ideal for use in machinery and equipment where design constraints demand a small footprint without compromising on strength, such as automotive transmissions, hydraulic pumps, and industrial gearboxes.SpecificationProductNeedle Roller BearingTypeNA Series/RNA Series/NK Series/NKI Series/NKS SeriesPlace of OriginChina,shandongStructureNeedle BearingBrandOEM ODMMaterialGcr15 steel;Bearing steelSizeStandard size, customizableDelivery time7-30 days depends on quantity neededServiceOEM service, according to customer requirementsQualityLarge bearing capacity, fine mass.Other ModelsHK needle roller bearingNew modelDimensions(mm)Weight(kg)d(mm)D(mm)B(mm)Bore diameterOutsidediameterWidth174012HK20102026200.011204714HK20122026120.013255215HK20162026160.019306216HK20202026200.023357217HK20302026300.035408018HK22102228100.012458519HK22122228120.014509020HK22162228160.01985510021HK22202228200.00336011022HK25122532120.00346512023HK25162532160.00487012524HK25202532200.00457513025HK25262532260.00578014026HK25382532380.009103511HK28162835160.0103123712HK28202835200.01154213HK30123037120.0102174714Bearing No.Boundary dimensions(mm)Basic load ratings(N)Limiting speeds(rpm)Mass(g)FwDCCrCorOilNAV40021532171080029800450076NAV4003173518170037900430094NAV400420422228150609003900170NAV400525472233800708003700195NAV400630552549900965003500299NAV4007356227476001228003100402NAV4008406828499001379002700482NAV4009457530525001535002600617NAV4010508030557001660002500669NAV40115590356850022580023001030NAV40126095357540023900021001087NAV401365100357950025690019001156NAV401470110409880035490017001666NAV4015751154510180037290016001762NAV4016801254510290037350015002450NAV4017851304510380037480014002500ShaftBearing No.Boundary Dimensions(mm)Basic Load Rating(N)Limiting SpeedFwEwBcCrCorOil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ompany ProfileShandong Xinsheng Bearing Co., Ltd. is a distinguished player in the bearing manufacturing industry, strategically located in Jinan, Shandong.
