通常，轴由径向和轴向两个轴承支承。一侧的轴承称为固定端轴承。它同时承受径向和轴向载荷，作为固定轴与轴承座之间的相对轴向位移。另一边叫做自.由端。它只承受径向载荷，可以相对轴向移动。Usually,theshaftissupportedbyradialandaxialbearings.Bearingsononesidearecalledfixedendbearings.Itbearsbothradialandaxialloadsandactsastherelativeaxialdisplacementbetweenthefixedshaftandthebearingseat.Theothersideiscalledself-end.Itonlybearsradialloadsandcanmoverelativelyaxially.固定端淮安INA轴承bi须与轴和轴承箱同时固定。***适合的轴承是能承受复杂载荷的径向轴承，如深沟球轴承、调心滚子轴承、双列或对角接触球轴承或圆锥滚子轴承。径向轴承的组合在简单的径向载荷下，如圆柱滚子轴承内圈和外圈有ribless，深沟球轴承或四点接触球轴承或双向推力轴承，也可以作为固定端轴承使用。此时，Di二轴承提供双向轴向***，但bi须与轴承箱安装在一定的径向间隔。当自.由端轴承的长度因热膨胀而改变时，轴承内不会发生挤压。轴向位移可能发生在轴承内部，以及轴承环和淮安INA轴承座。ThefixedendofHuaianINAbearingBishallbefixedsimultaneouslywiththeshaftandbearingbox.***issuitableforbearingsthatcanwithstandcomplexloads,suchasdeepgrooveballbearings,self-aligningrollerbearings,doublerowordiagonalcontactballbearingsortaperedrollerbearings.Thecombinationofradialbearingsundersimpleradialloads,suchasriblessinnerandouterringsofcylindricalrollerbearings,deepgrooveballbearingsorfour-pointcontactballbearingsorbi-directionalthrustbearings,canalsobeusedasfixed-endbearings.Atthistime,Di2bearingsprovidebidirectionalaxialpositioning,butBimustbeinstalledatacertainradialintervalwiththebearingbox.Whenthelengthofself-endbearingischangedbythermalexpansion,noextrusionwilloccurinthebearing.Axialdisplacementmayoccurinsidethebearing,aswellasthebearingringandHuaianINAbearingseat.“十字***”是指轴承的配置，每个轴承都位于一个方向和相反的方向。这种组合主要用于短轴。所有径向轴承，包括深沟和角接触球轴承、圆锥滚子轴承和NJ圆柱滚子轴承，都适合承受至少一个方向的轴向载荷。在某些情况下，当使用角接触球轴承或圆锥滚子轴承时，bi须施加预紧力。"Crosspositioning"referstotheconfigurationofbearings,eachbearingislocatedinonedirectionandtheoppositedirection.Thiscombinationismainlyusedforshortaxes.Allradialbearings,includingdeepgrooveandangularcontactballbearings,taperedrollerbearingsandNJcylindricalrollerbearings,aresuitableforbearingatleastonedirectionofaxialload.Insomecases,whenangularcontactballbearingsortaperedrollerbearingsareused,Biisrequiredtoexertpreload.在轴承选型阶段，需要考虑许多因素(如载荷、硬度、工作环境等)。一个好的轴承设计首先会使轴承达到它的***大寿命。Inthestageofbearingselection,manyfactors(suchasload,hardness,workingenvironment,etc.)needtobec***idered.Agoodbearingdesignwillfirstmakethebearingreachits***life.2.正确储存，淮安INA轴承应在安装前按原包装保存。它需要保持在一个干净，潮湿和相对恒定的温度环境。滚动轴承应远离灰尘、水和腐蚀性***。振动和振动会对轴承的机械性能造成永.久性的***，因此在加工和储存过程中应避免振动。一般来说，轴承应保持水平。一些较重的轴承在长期垂直放置后会因自身重量而变形。此外，润滑(或密封)轴承需要特别小心，因为油脂的密度在长期储存后会发生变化。轴承首.次使用时，会产生一定程度的旋转噪声。因此，这种轴承的保质期应根据***先出原则进行控制。2.Properstorage,HuaianINAbearingsshouldbestoredintheoriginalpackagingbeforeinstallation.Itneedstobekeptinaclean,humidandrelativelyc***tanttemperatureenvironment.Generallyspeaking,bearingsshouldbekeptlevel.Somehe***ierbearingswillbedeformedbytheirownweightafterlong-termverticalplacement.Inaddition,lubricated(orsealed)bearingsrequirespecialcarebecausethedensityofgreasechangesafterlong-termstorage.Whenthebearingheadisusedforasecondtime,itwillproduceacertaindegreeofrotationalnoise.Therefore,theshelflifeofthiskindofbearingshouldbecontrolledaccordingtothefirst-in-first-outprinciple.文章来自：淮安SKF轴承www.wh-文章来自：淮安INA轴承a-文章来自：淮安NSK轴承***：524085168电话：0510-81207777手机：13311666672/13395185757)
