圆柱滚子与滚道为线接触
轴承。负荷能力大,主要承受径向负荷。滚动体与套圈挡边摩擦小,适于高速旋转。根据套圈有无挡边,可以分有NU、NJ、NUP、N、NF等单列圆柱滚子轴承,及NNU、NN等双列圆柱滚子轴承。该轴承是内圈、外圈可分离的结构。内圈或外圈无挡边的圆柱滚子轴承,其内圈和外圈可以向轴向作相对移动,所以可以作为自由端轴承使用。在内圈和外圈的某一侧有双挡边,另一侧的套圈有单个挡边的圆柱滚子轴承,可以承受一定程度的一个方向轴向负荷。一般使用钢板冲压保持架,或铜合金车制实体保持架。但也有一部分使用聚酰胺成形保持架。单列圆柱滚子轴承通常是只受径向力,与同尺寸球轴承相比,径向承载能力提高1.5-3倍,刚性好、耐冲击,它特别适用于刚性支承的、又支承短轴、受热伸长而引起轴向位移的轴和安装拆卸需要分离型轴承之机器附件。主要用于大型电机、机床主轴、发动机前后支承轴、火车客车车箱轴支承、柴油机曲轴、汽车拖拉机变速箱等。单列圆柱滚子轴承,包括外圈、内圈锁紧圈和保持架。外圈的外壁面中间设有环形应力槽,外圈的外壁上有多个环形锁紧槽,锁紧圈的形状和大小与环形锁紧槽的形状和大小相适应。环形锁紧槽内装设有锁紧圈。外圈内壁的环面上与应力槽相对应部位设有环形保持架引导槽。本实用新型具有组装方便、承载负荷大,极限转速高、可靠性强、使用寿命长等优点。推力圆柱滚子轴承常组合成高刚度轴承配置,可以毫无困难地承受重载荷和振动载荷。这种轴承可以承受单方向很大的轴向载荷,但是不能承受径向载荷,它们没有自动调心能力。推力圆柱滚子轴承可以拆分为推力圆柱滚子和保持架组件、轴圈和座圈。811系列和812系列推力圆柱滚子轴承由推力圆柱滚子和保持架组件、轴圈和座圈组成,最重要的零部件是推力圆柱滚子和保持架组件。轴承型号外型尺寸额定负荷(kN)质量dDB动负荷静负荷kgN00402003103428030010.2NU10402003105140536014.3NJ10402003105140536014.7N2402003605859552526.8NU2402003605859552526.5NJ2402003605859552527.1N23402004201381570150094.5NU334020042016519202020118NU10442203405647037119.3NJ10442203405646041519.6NU1044N2203405647037118.9NU64422035098.421070105037.5N2442204006572565036.7NU2442204006572565035NJ2442204006572565035.4NU22442204001081080108062.2NU3442204608811094573.4NU2344E22046014519101870114N00482403603738839214.7NU10482403605649748020.4NJ10482403605649748821NU2482404407290081546.9NJ2482404407290081549.6NU348240500951350113097.7NUP24824044072880134548.2NU348240500951340206082.4N6502503805060064319.8N00522604004455260322.7NU10522604006562163029.4NUP10522604006562163029.5N10522604006562163030.8NU10522604006562163029.4NU25226048080107096567.1NU10562804206562762533.4NU10603004607485595244.4NJ10603004607481578045.1NU30603004601181690180072NU260300540851290120086.9NU36030062010920101840166NJ10643204807482080047.8NU10643204807484889547N00683405205799593545.5N668340530133.2516601810117NU2272E36065017027502920263NU237236075022447605400485N28763804806064775624.6NU19804005406578598842.7NU1080400600901350146088.8NU308040060014821503300144.5N218040065014528303030190NU6884405464641347626.5N118844072012223202220191N2992460620951340206082.4NU2992460620951340206084NU29/5005006701002000241099.5NU29/53053071010621702530123N19/63063085010018502530160NU29/63063085012830504260206NU6/70070093016032004580295N19/71071095010623003250205NU19/71071095010623003250207N6/840840104012525305290240NU29/950950125017052709120563N39/9509501250224678010500745双列圆柱滚子轴承NN3052K260400104969181047.1NN3052260400104969181048.5NN3056K2804201061020195049.1NN30562804201061020195049.87NN30603004601181180225071.7NN3060/Y13004601181180225071.2NN3060K3004601181180225069.6NN3064K3204801211250245075NN3068K34052013315603020101NN306834052013315603020104NN3072K36054013416303240106NN3076K38056013515903240110NN307638056013515903240114NN3176V38062019427005800221NN3980K4005401081240240071.3NN3080K40060014819803660143NN308040060014819803660147NN3092K46068016824705070204NN39/56056075014023704860188NN6/56056078018024006400266NN30/560K56082019524606560341NN30/67067098028046209360597四列圆柱滚子轴承 FCD649629032048029034207200186FCD6496350320480350470010200225FCD6896350340480350434010200230FCD74104380370520380443010600253FCD96140400480700400660015100508FCD1001344505006704507830202000441FCD11416359457081559411400297001070FCD152216788760108078820100555002403FCD166216710830108071018000500001746FCD190260850950130085029000920003523
