style="text-indent:25px">辨別雙列圓柱滾子設備軸承的質量，我們通常從以下幾個方面進行：外包裝是否明晰：雙列圓錐滾子軸承一般情況下，正規(guī)廠家生產的品牌都有自己專門的設計人員對外包裝進行設計，并且安排生產條件過關的工廠進行制作生產，因此，產品的包裝無論從線條到色塊都應該是非常清晰，毫不含糊。鋼印字是否清晰：每一個軸承產品都會在軸承產品體上印有其品牌字樣、標號等。雖然字體非常小，但是正規(guī)廠家生產的產品都采用了鋼印技術印字，而且在未經過熱處理之前就進行壓字，因此其字體雖然小，但是凹得深，非常清晰。而通常情況下，仿冒產品的字體非但模糊，由于印字技術粗糙，字體浮于表面，有些甚至輕易地就可以用手抹去或者手工痕跡嚴重。NN3032K雙列圓柱滾子系列軸承供貨商圓柱滾子與滾道呈線接觸，徑向載荷能力大。</p><div

style="text-indent:25px">機床主軸常用軸承有五大類：深溝球軸承，角接觸球軸承，雙向推力角接觸球軸承，雙列圓柱滾子軸承，圓錐滾子軸承。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速。軸承中的兩列滾子以交叉方式排列，旋轉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，內圈可分離，其中NN30K/W33和NNU49K/W33系列內圈為錐孔（錐度1：12），與主軸的錐形軸頸相配合，軸向移動內圈，可使內圈脹大，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。對內圈可分離的NNU49系列軸承，一般在內圈裝上主軸后再作滾道的精加工，以獲得高的主軸旋轉精度。</p><p style="text-indent:25px">高精度圓柱滾子軸承截面小，承載能力高，變形小。因此，普遍應用于機床主軸或徑向負荷較重、剛性要求較高的主軸上,雙列圓柱滾子軸承有NN和NNU兩種結構，直徑系列分別為30系列和49系列。NN型結構:外圈無擋邊,內圈有雙擋邊。NNU型結構:內圈無擋邊，外圈有雙擋邊。軸可以軸向延伸。NNU49系列軸承截面比NN30系列小、主軸系的剛性高，但承載能力小。內孔帶1:12錐度的軸承,安裝后可以調整軸承的間隙或予載荷。無錫哈配機電設備有限公司致力于為客戶打造生態(tài)化互聯網平臺，為客戶提供一站式整體解決方案。常用的圓柱滾子軸承有哪些？</p><div
