推力球轴承推力球轴承组成：　　推力球轴承由座圈、轴圈和钢球保持架组件三部分构成。　　与轴配合的称轴圈，与外壳配合的称座圈。推力球轴承种类：　　接受力情况分单向推力球轴承和双向推力球轴承。　　单向推力球轴承，可承受单向轴向负荷。　　双向推力球轴承，可承受双向轴向负荷。双向推力球轴承，其中圈与轴配合。座圈的安装面呈球面的轴承，具有调心性能，可以减少安装误差的影响。　　推力球轴承不能承受径向负荷，极限转速较低。推力球轴承的用途：　　只适用于承受一面轴向负荷、转速较低的机件上，例如起重机吊钩、立时水泵、立时离心机、千斤顶、低速减速器等。轴承的轴圈、座圈和滚动体是分离的，可以分别装拆。轴承型号外形尺寸(mm)重量(kg) dDH51100102490.019351101122690.021451102152890.024351103173090.0253511042035100.038511052542110.056511063047110.066511073552120.083511084060130.12511094565140.15511105070140.16511115578160.24511126085170.29511136590180.324511147095180.365111575100190.3925111680105190.4335111785110190.465111890120220.65651120100135251.051122110145251.0851124120155251.251126130170301.8051128140180312.1051130150190312.20     512001026110.0293512011228110.0324512021532120.0444512031735120.0506512042040140.0733512052547150.109512063052160.138512073562180.22512084068190.27512094573200.32512105078220.39512115590250.619512126095260.695121365100270.755121470105270.795121575110270.8155121680115280.9255121785125311.35121890135351.7751220100150382.451222110160382.651224120170392.951226130190454.3251228140200464.6          513042047180.150513052552180.171513063060210.265513073568240.378513084078260.55513094585280.695131050953115131155105351.345131260110351.435131365115361.575131470125401.955131575135442.75131680140442.85131785150493.75131890155503.951320100170555.1     514052560240.34514063070280.36514073580320.82514084090361.185140945100391.645141050110431.99
