圓柱滾子與滾道為線接觸
軸承。負(fù)荷能力大，主要承受徑向負(fù)荷。滾動(dòng)體與套圈擋邊摩擦小，適于高速旋轉(zhuǎn)。根據(jù)套圈有無擋邊，可以分有NU、NJ、NUP、N、NF等單列圓柱滾子軸承，及NNU、NN等雙列圓柱滾子軸承。該軸承是內(nèi)圈、外圈可分離的結(jié)構(gòu)。內(nèi)圈或外圈無擋邊的圓柱滾子軸承，其內(nèi)圈和外圈可以向軸向作相對移動(dòng)，所以可以作為自由端軸承使用。在內(nèi)圈和外圈的某一側(cè)有雙擋邊，另一側(cè)的套圈有單個(gè)擋邊的圓柱滾子軸承，可以承受一定程度的一個(gè)方向軸向負(fù)荷。一般使用鋼板沖壓保持架，或銅合金車制實(shí)體保持架。但也有一部分使用聚酰胺成形保持架。單列圓柱滾子軸承通常是只受徑向力，與同尺寸球軸承相比，徑向承載能力提高1.5-3倍，剛性好、耐沖擊，它特別適用于剛性支承的、又支承短軸、受熱伸長而引起軸向位移的軸和安裝拆卸需要分離型軸承之機(jī)器附件。主要用于大型電機(jī)、機(jī)床主軸、發(fā)動(dòng)機(jī)前后支承軸、火車客車車箱軸支承、柴油機(jī)曲軸、汽車拖拉機(jī)變速箱等。單列圓柱滾子軸承，包括外圈、內(nèi)圈鎖緊圈和保持架。外圈的外壁面中間設(shè)有環(huán)形應(yīng)力槽，外圈的外壁上有多個(gè)環(huán)形鎖緊槽，鎖緊圈的形狀和大小與環(huán)形鎖緊槽的形狀和大小相適應(yīng)。環(huán)形鎖緊槽內(nèi)裝設(shè)有鎖緊圈。外圈內(nèi)壁的環(huán)面上與應(yīng)力槽相對應(yīng)部位設(shè)有環(huán)形保持架引導(dǎo)槽。本實(shí)用新型具有組裝方便、承載負(fù)荷大，極限轉(zhuǎn)速高、可靠性強(qiáng)、使用壽命長等優(yōu)點(diǎn)。推力圓柱滾子軸承常組合成高剛度軸承配置，可以毫無困難地承受重載荷和振動(dòng)載荷。這種軸承可以承受單方向很大的軸向載荷，但是不能承受徑向載荷，它們沒有自動(dòng)調(diào)心能力。推力圓柱滾子軸承可以拆分為推力圓柱滾子和保持架組件、軸圈和座圈。811系列和812系列推力圓柱滾子軸承由推力圓柱滾子和保持架組件、軸圈和座圈組成，最重要的零部件是推力圓柱滾子和保持架組件。軸承型號外型尺寸額定負(fù)荷(kN)質(zhì)量dDB動(dòng)負(fù)荷靜負(fù)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雙列圓柱滾子軸承NN3052K260400104969181047.1NN3052260400104969181048.5NN3056K2804201061020195049.1NN30562804201061020195049.87NN30603004601181180225071.7NN3060/Y13004601181180225071.2NN3060K3004601181180225069.6NN3064K3204801211250245075NN3068K34052013315603020101NN306834052013315603020104NN3072K36054013416303240106NN3076K38056013515903240110NN307638056013515903240114NN3176V38062019427005800221NN3980K4005401081240240071.3NN3080K40060014819803660143NN308040060014819803660147NN3092K46068016824705070204NN39/56056075014023704860188NN6/56056078018024006400266NN30/560K56082019524606560341NN30/67067098028046209360597四列圓柱滾子軸承 FCD649629032048029034207200186FCD6496350320480350470010200225FCD6896350340480350434010200230FCD74104380370520380443010600253FCD96140400480700400660015100508FCD1001344505006704507830202000441FCD11416359457081559411400297001070FCD152216788760108078820100555002403FCD166216710830108071018000500001746FCD190260850950130085029000920003523
