style="text-indent:25px">雙列圓柱滾子軸承：這類軸承能承受較大的徑向載荷并允許有較高的轉(zhuǎn)速。軸承中的兩列滾子以交叉方式排列，旋轉(zhuǎn)時波動頻率可比單列軸承提高一倍，振幅降低70％。常用的此類軸承有兩種形式：NN30/W33、NN30K/W33兩個系列軸承內(nèi)圈帶擋邊，外圈可分離；NNU49/W33、NNU49K/W33兩個系列軸承外圈帶擋邊，內(nèi)圈可分離，其中NN30K/W33和NNU49K/W33系列內(nèi)圈為錐孔（錐度1：12），與主軸的錐形軸頸相配合，軸向移動內(nèi)圈，可使內(nèi)圈脹大，以減小軸承游隙甚至預緊軸承。圓柱孔軸承通常采用熱裝，利用過盈配合減小軸承游隙，或者達到預緊的目的。對內(nèi)圈可分離的NNU49系列軸承，一般在內(nèi)圈裝上主軸后再作滾道的精加工，以獲得高的主軸旋轉(zhuǎn)精度。</p><p style="text-indent:25px">圓柱滾子軸承的徑向間隙調(diào)整的方法，常用調(diào)整滿裝圓柱滾子軸承徑向間隙的方法如下： 1、對于圓筒形和橢圓形軸瓦的側(cè)隙可采用手工研刮或軸承中分面加墊車削后修刮的方法調(diào)整。 2、對于圓筒形和橢圓形軸瓦的頂隙可采用手工研刮或情況允許時對軸承中分面加墊的方法調(diào)整。 3、對于多油楔固定式軸瓦，原則上不允許修刮和調(diào)整軸瓦間隙，間隙不合適時應更換新瓦。 4、對于多油楔可傾式軸瓦，不允許修刮瓦塊，間隙不合適時應更換因瓦塊。對厚度可調(diào)的瓦塊，可通過在瓦背后調(diào)整塊下加不銹鋼墊，或減薄調(diào)整塊厚度的方法調(diào)整瓦量。注意對多油楔可傾式軸瓦，同組瓦塊間厚度誤差應小于0.01mm。高精度圓柱滾子軸承可應用于機床主軸或徑向負荷較重、剛性要求較高的主軸上。</p><div

style="text-indent:25px">雙列圓柱滾子軸承雙列圓柱滾子軸承有圓柱和圓錐孔（后置代號K）兩種結(jié)構(gòu)。主要有2種類型：NNU設計和NN設計。NN型設計內(nèi)圈雙擋邊而外圈無擋邊。NNU型設計內(nèi)圈無擋邊而外圈有雙擋邊。圓錐孔結(jié)構(gòu)可以在安裝時，起到調(diào)整徑向游隙的作用。雙列圓柱滾子軸承允許軸與軸承座之間存在一定的的軸向位移，可以被用作非定位軸承。該類軸承具有結(jié)構(gòu)緊湊、剛性大、承載能力大、受載后變形小等優(yōu)點，特別適用于機床主軸支承。雙列圓柱滾子軸承的保持架多采用車制實體保持架。索倫軸承（外圈帶止動槽的雙列圓柱滾子軸承）兩側(cè)裝有聚亞安脂（AU）制成的接觸式密封圈。NN3013KTN/W33雙列圓柱滾子系列軸承現(xiàn)貨</p><p

style="text-indent:25px">軸承是用來支撐的部件，也是用來支承軸上回轉(zhuǎn)的零件，作為當代機械重要零件，應用普遍。雙列圓柱滾子軸承是軸承的其中一種。下面，我們就來介紹下軸承常見的幾種性能： 1. 耐磨性能：軸承工作時，套圈、滾動體和保持架之間不僅發(fā)生滾動摩擦，而且也會發(fā)生滑動摩擦，從而使軸承零件不斷地磨損。為了減少軸承零件的磨損，保持軸承精度穩(wěn)定性，延長使用壽命，軸承應有很好的耐磨性能。 2. 接觸疲勞強度：軸承在周期負荷的作用下，接觸表面很容易發(fā)生疲勞破壞，即出現(xiàn)龜裂剝落，這是軸承的主要損壞形式。因此，為了提高軸承的使用壽命，軸承必須具有很高的接觸疲勞強度。蘇州NN3020/W33雙列圓柱滾子系列軸承訂購</p><p
