调心球轴承结构它分为圆柱孔和圆锥孔两种结构，保持架的材质有钢板、合成树脂等。其特点是外圈滚道呈球面形，具有自动调心性，可以补偿不同心度和轴挠度造成的误差，但其内、外圈相对倾斜度不得超过3度。一般常见的调心球轴承是双列调心球轴承（也叫自动调心球轴承），由一个大球面沟道的外圈、一个双沟内圈、两列钢球和保持架组成。旋转时钢球、保持架、内圈对于外圈心轴可作一定程度的自由倾斜（具有调心性是它的特点），可自动调整轴和轴承箱因加工、安装不当发生的轴心偏移。但一般最大的轴线倾斜度不得大小3度。调心球轴承还有单列满球，无保持架，带双面防尘盖的结构。这种轴承孔径不大于10mm，常用于飞机机架构件中。轴承一次性润滑，不用再润滑了。调心球轴承产品特性：主要承受径向载荷，同时可承受较小轴向载荷。轴（外壳）的轴向位移限制在游隙限度内，具有自动调心性能，允许内、外围相对倾斜不大的条件下正常工作，适用于支承座孔不能严格保证同轴度的部件中。NTN超高速单列及双列向心推力球轴承BNT型HSB型BNT000HSB910CHSB920CBNT200HSB010CHSB020CBNT001HSB911CHSB921CBNT201HSB011CHSB021CBNT002HSB912CHSB922CBNT202HSB012CHSB022CBNT003HSB913CHSB924CBNT203HSB013CHSB024CBNT004HSB914CHSB926CBNT204HSB014CHSB026CBNT005HSB915CHSB928CBNT205HSB015CHSB028CBNT006HSB916CHSB930CBNT206HSB016CHSB030CBNT007HSB917CHSB932CBNT207HSB017CHSB032CBNT008HSB918CHSB934CBNT208HSB018CHSB034CBNT009HSB919CBNT209HSB019C四列圆柱滚子轴承4R24374R34324R44134R24384R34254R44194R26284R34334R44264R28234R34314R44254R29064R36254R44204R29084R36284R44164R30314R36184R44304R30294R38204R44284R30404R38184R44294R30394R38214R46144R32244R38234R46114R32264R40394R48114R32324R40264R48064R32254R40374R48074R34264R40414R50084R34294R40284R52174R34234R42064R52134R54054R56114R56124R56054R58064R5805四列圆柱滚子轴承E-4R6014E-4R8201E-4R10602E-4R6017E-4R8403E-4R11001E-4R6015E-4R8404E-4R11202E-4R6020E-4R8401E-4R11402E-4R6018E-4R8801E-4R12003E-4R6019E-4R9211E-4R12002E-4R6202E-4R9209E-4R12001E-4R6414E-4R9216E-4R12202E-4R6411E-4R9607E-4R13005E-4R6412E-4R9609E-4R13003E-4R6406E-4R9604E-4R13201E-4R6603E-4R10010E-4R13802E-4R6605E-4R10016E-4R14003E-4R6811E-4R10006E-4R14205E-4R6804E-4R10011E-4R14501E-4R7203E-4R10008E-4R15001E-4R7405E-4R10015E-4R15002E-4R7404E-4R10201E-4R15204E-4R7505E-4R10202E-4R15207E-4R7607E-4R10403E-4R15203E-4R7604E-4R10102E-4R16004E-4R8007E-4R10603E-4R16005E-4R8010E-4R10601E-4R16406E-4R16405E-4R16403E-4R16801E-4R17001E-4R17003E-4R17004E-4R17002E-4R17201E-4R18001E-4R18401E-4R20001E-4R20002E-4R20601E-4R24002圆锥滚子轴承180KBE031+L260KBE032+L300KBE033+L30230(7230)32024(2007124)32026X/DF32026(2007126)32028X32034X32036X32060X232064X232220(7520E)32228J232230J232232J2(7532)32232J2/DF32234(7534)32236J232240J232252J232940X2A/P532944579905A97517(352217)52400/52637D803370(渗碳钢)442212TDO/ZD32097132(352032)BT2B3327582097732(352132)67780/67720B67790/67720B67985/6792067983/67920CD687/672D71433/7175080176/8021788925/881269285/9220D93750/93125V93800/93125V93825/93125V96925/9614098400/98789DBT2B332830(TDO/D)2097968BT4B328209330822EE671801/672873H239640/H239610HM252343/HM252310DHM262749TD/HM262710HM743345/HM743310CDHM921343/HM921310CDHM926747/HM926710DHM926749/HM926710DL217849/L217810DL540049/L540010L814749/L814710DL853049/L853010L860049/L860010L865547/L865512LM761649DW/LM761610LM869448/LM869410CDM249749/M249710CDM349549/M349510802003.H122AG802101.A250.300调心滚子轴承22211CCK/W3322215CC/W3322215CC/W3322218CC/W3322218CCK/W3322220CC/W3322222CC/W3322224CC/W3322224CAME4S1122226CC/W3322228CC/W3322228CCK/W3322230CC/W3322232CC/W3322232CA/W3322234CC/W3322236CC/W3322238CC/W3322238CA/W3322238CAK/W3322240CC/W3322240CA/W3322248BMB/W3322248BKMB/W3322317CC/W3322318CC/W3322319CC/W3322320CAK22320MB/W33(53620)22320CC/W3322322CC/W3322322CA/W3322322CAK/W3322324CC/W3322324CC/W3322324CCK/W3322326CC/W3322326CA/W33C322326CAK/W33C322328CC/W3322328CCK/W3322328CA/W3322328CAK/W3322330CC/W33精密回转轴承YRT120YRT150020.25.560.002.04回转轴承系列VI160288VU200405关节轴承系列GE320DWGE400DW)
