南京NSK轴承类型包括深沟球轴承，圆柱滚子轴承，球面滚子轴承，圆锥滚子轴承，角接触球轴承，滚针轴承和许多其余类型。此外，还提供了一系列的轴承维护工具、润滑脂和轴承监测仪器，使轴承用户更加有利可图，无忧操作。NanjingNSKbearingtypesincludedeepgrooveballbearings,cylindricalrollerbearings,sphericalrollerbearings,taperedrollerbearings,angularcontactballbearings,needlerollerbearingsandmanyothertypes.Inaddition,aseriesofbearingmaintenancetools,greaseandbearingmonitoringinstrumentsareprovidedtomakebearingusersmoreprofitableandworry-freeoperation.它只能承受一个方向的轴向载荷，不能承受径向载荷。由于轴向载荷分布均匀，球体承载能力大，但工作温度急剧上升，极限转速低。Itcanonlybearaxialloadinonedirectionandcannotbearradialload.Becauseoftheuniformaxialloaddistribution,thebearingcapacityofthesphereislarge,buttheworkingtemperaturerisessharplyandthelimitspeedislow.推力球轴承不制约轴或壳体的径向运动，但可以制约南京NSK轴承和壳体在一个方向上的轴向运动。因此，这种轴承通常用于深沟球轴承。在安装过程中，轴孔和壳体孔的轴线需要保持同心，否则轴承会因应力集中而过早损坏。Thrustballbearingsdonotrestricttheradialmotionoftheshaftorshell,butcanrestricttheaxialmotionofNanjingNSKbearingandshellinonedirection.Therefore,thisbearingisusuallyusedindeepgrooveballbearings.Intheinstallationprocess,theaxisoftheshaftholeandshellholemustbekeptconcentric,otherwisethebearingwillbedamagedprematurelybecauseofstressconcentration.为了消掉这种不好的现象，可以在座环的外径和壳体孔之间留有0.5至1mm的径向间隙。南京NSK轴承的中点线应垂直于壳体的支承面。轴不应该倾斜或偏转。否则，轴承会因负载分配不均而过早损坏。Toeliminatethisundesirablephenomenon,aradialgapof0.5to1mmcanbeleftbetweentheouterdiameteroftheseatringandtheshellhole.ThemidpointlineofNSKbearinginNanjingshouldbeperpendiculartothesupportingsurfaceoftheshell.Theshaftshouldnotbetiltedordeflected.Otherwise,thebearingwillbedamagedearlyduetounevenloaddistribution.在安装推力球轴承时，检查轴和中间线的垂直度。其方法是将转台固定在壳体的端面上，使转台的接触使轴承在轴承滚道上旋转，并观察转台指针。如果指针倾斜，则意味着轴环和轴线不是垂直的。Wheninstallingthrustballbearings,checktheperpendicularityoftheshaftandthemiddleline.Themethodistofixtheturntableontheendfaceoftheshell,sothatthecontactoftheturntablemakesthebearingrotateonthebearingraceway,andobservetheturntablepointer.Ifthepointeristilted,itmeansthattheaxleringandtheaxisarenotperpendicular.当南京NSK轴承箱孔较深时，也可通过千米检查延长。当推力球轴承正确安装时，座圈可自动适应滚动元件的滚动，确保滚动元件在上、下滚道上滚动。如果载荷反向，不仅轴承工作异常，而且表面磨损严重。由于轴环与阀座环的区别不明显，装配时要小心，不要出错。WhentheNSKbearingboxinNanjingisdeep,itcanalsobeextendedbykilometerinspection.Whenthethrustballbearingisproperlyinstalled,theseatringcanautomaticallyadapttotherollingoftherollingelementtoensurethattherollingelementrollsontheupperandlowerraceways.Iftheloadisreversed,notonlythebearingworkisabnormal,butalsothesurfacewearisserious.Becausethedifferencebetweentheaxleringandtheseatringisnot***ious,becarefulwhenassembling,donotmakemistakes.另外，推力球轴承座圈与轴承座孔之间应留有0.2-0.5mm的间隙，以补偿由于零件的加工和安装不准确而引起的误差。当南京NSK轴承环的中间在运行中偏移时，间隙可自动调整，避免接触摩擦，使其正常运行。否则会造成严重的轴承损坏。Inaddition,agapof0.2-0.5mmshouldbeleftbetweentheseatringofthrustballbearingandthebearingseatholetocompensatefortheerrorscausedbyinaccuratemachiningandinstallationoftheparts.WhenthecenterofNanjingNSKbearingringisoffsetinoperation,theclearancecanbeadjustedautomaticallyto***oidcontactfrictionandmakeitrunnormally.Otherwise,itwillcauseseriousbearingdamage.因此，在安装推力球轴承时，应注意以下几点。Therefore,wheninstallingthrustballbearings,weshouldpayattentiontothefollowingpoints.（1）根据0.1～0.5mm轴承直径和直径的差异，对轴承套圈和松动套圈进行区分。(1)Accordingtothedifferenceofdiameteranddiameterbetween0.1-0.5mmbearings,thebearingringsandlooseringsaredistinguished.（2）区分***的静态部分（即不移动的部分，主要是指配体）。(2)distinguishthestaticpartofanorganization(i.e.thepartthatdoesnotmove,mainlyreferstotheligand).（3）在任何情况下，轴承的松动环应始终依赖于固定部分的端部。(3)inanycase,thelooseningringofthebearingshouldalwaysdependontheendofthefixedpart.文章来自：南京SKF轴承www.wh-Thearticleisfrom:NanjingSKFbearingwww.wh-文章来自：南京INA轴承a-Thearticleisfrom:NanjingINAbearinga-文章来自：南京NSK轴承Thearticleisfrom:NanjingNSKbearing)
