通常，轴由两个泰国SKF轴承在径向和轴向上支撑。一侧的轴承称为固定端轴承。它承受径向和轴向载荷，并作为固定轴与轴承箱之间的相对轴向位移。另一端称为自*由端，只承受径向载荷，轴向可相对移动。Normally,theshaftissupportedbytwoThailandSKFbearingsinradialandaxialdirection.Thebearingononesideiscalledfixedendbearing.Itbearsradialandaxialloadsandactsastherelativeaxialdisplacementbetweenthefixedshaftandthebearingbox.Theotherendiscalledtheself*end,whichonlybearsradialload,andtheaxiallycanmoverelatively.固定端轴承必*须与轴和泰国SKF轴承箱同时固定。更适合的轴承是在复杂载荷下的径向轴承，如深沟球轴承、自对准滚子轴承和双列或对角接触球轴承或圆锥滚子轴承。简单径向载荷下的径向轴承，如带内外圈的圆柱滚子轴承，当与深沟球轴承或四点接触球轴承或双向推力轴承组合时，也可用作固定端轴承。此时，第*二轴承提供双向轴向***，但必*须与轴承箱安装在一定径向间隔处。当轴膨胀时，自*由端轴承的轴承不会由于热膨胀而被挤压。轴承、轴承套圈和轴承座可能发生轴向位移。ThefixedendbearingmustbefixedatthesametimeastheaxleandtheThailandSKFbearingbox.Moresuitablebearingsareradialbearingsundercomplexloads,suchasdeepgrooveballbearings,self-aligningrollerbearingsanddoublerowordiagonalcontactballbearingsortaperedrollerbearings.Radialbearingsundersimpleradialloads,suchascylindricalrollerbearingswithinnerandouterrings,canalsobeusedasfixed-endbearingswhencombinedwithdeepgrooveballbearingsorfour-pointcontactballbearingsorbi-directionalthrustbearings.Atthispoint,thesecondbearingprovidesbidirectionalaxialpositioning,butmustbeinstalledatacertainradialintervalwiththebearingbox.Whentheshaftexpands,thebearingfromtheendbearingwillnotbeextrudedduetothermalexpansion.Axialdisplacementmayoccurinbearings,bearingringsandbearinghousings.“交叉固定”是指轴承结构，每个泰国SKF轴承在一个方向和相反方向。这种组合主要用于短轴。所有径向轴承，包括深沟槽和角接触球轴承、圆锥滚子轴承和NJ圆柱滚子轴承，可以在一个方向上承受至少一个轴向载荷。在某些情况下，当使用角接触球轴承或圆锥滚子轴承时，必*须施加预紧力。"Crossfixation"referstothebearingstructure,eachThailandSKFbearinginonedirectionandtheoppositedirection.Thiscombinationismainlyusedforshortaxis.Allradialbearings,includingdeepgrooveandangularcontactballbearings,taperedrollerbearingsandNJcylindricalrollerbearings,canbearatleastoneaxialloadinonedirection.Insomecases,whenusingangularcontactballbearingsortaperedrollerbearings,itisnecessarytoapplypretighteningforce.轴承转速：滚动轴承的运行速度受允许工作温度的限*制。低摩擦轴承产生低内热，**适合高速运转。深沟球轴承和自调心球轴承在纯径向载荷或组合载荷下能承受比其它轴承更高的转速。精*密角接触球轴承和陶瓷滚子或深沟球泰国SKF轴承甚至可以实现更高的速度。由于设计的原因，推力轴承的速度不能达到径向轴承的速度。Bearingspeed:therunningspeedofrollingbearingsislimitedbyallowableworkingtemperature.Lowfrictionbearingsproducelowinternalheat,whichissuitableforhigh-speedoperation.Deepgrooveballbearingsandself-aligningballbearingscanwithstandhigherspeedthanotherbearingsunderpureradialloadorcombinedload.Precision*denseanglecontactballbearingsandceramicrollerordeepgrooveballThaiSKFbearingscanevenachievehigherspeed.Becauseofthedesignreason,thespeedofthethrustbearingcannotreachthespeedoftheradialbearing.轴承精度：要求高旋转精度的轴承结构（如机床主轴）及其在高速下的应用应该比普通等级的轴承具有更高的精度。它可以提供各种高精度轴承，包括单列角接触球轴承，单列和双列圆柱滚子轴承，以及单向和双向角接触推力球轴承。BearingAccuracy:Bearingstructuresrequiringhighrotationalaccuracy(suchasmachinetoolspindles)andtheirapplicati***athighspeedsshouldh***ehigheraccuracythanordinarygradebearings.Itcanprovideavarietyofhighprecisionbearings,includingsinglerowangularcontactballbearings,singlerowanddoublerowcylindricalrollerbearings,aswellasone-wayandtwo-wayangularcontactthrustballbearings.文章来自：泰州SKF轴承www.wh-Thearticleisfrom:TaizhouSKFbearingwww.wh-文章来自：泰州INA轴承a-Thearticleisfrom:TaizhouINAbearinga-文章来自：泰州NSK轴承Thearticleisfrom:TaizhouNSKbearing***：524085168电话：0510-81207777手机：13311666672/13395185757)
