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，軸承作為當(dāng)代機(jī)械重要零件，應(yīng)用較為普遍。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(shí)，套圈、滾動(dòng)體和保持架之間不只發(fā)生滾動(dòng)摩擦，而且也會(huì)發(fā)生滑動(dòng)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(zhǎng)使用壽命，軸承應(yīng)有很好的耐磨性能。2.接觸疲勞強(qiáng)度：軸承在周期負(fù)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(qiáng)度。</p><p style="text-indent:25px">雙列圓柱滾子軸承配合安裝時(shí)應(yīng)該注意以下四點(diǎn):(1)必須注意使軸承安裝和拆卸簡(jiǎn)便，省工省時(shí)省開支。(2)自由端軸承必須能與軸和軸承座孔的長(zhǎng)度變化相適應(yīng)，即必須具有適應(yīng)軸向位置在一定范圍內(nèi)游動(dòng)的能力。(3)套圈在其配合表面中不能沿切線方向滑動(dòng)，否則會(huì)損壞配合面。(4)軸承套圈圓周面應(yīng)有良好支承且受力均勻，以減少變形，并可充分發(fā)揮軸承的承載能力。無錫哈配機(jī)電設(shè)備有限公司始建于2012年，公司辦公地址位于太湖明珠魚米之鄉(xiāng)無錫，在公司發(fā)展壯大的6年里，我們始終為客戶提供良好的產(chǎn)品和技術(shù)支持、健全的售后服務(wù)。雙列圓柱滾子軸承（高剛性系列）采用新材料和新設(shè)計(jì)，可提高機(jī)床的性能。</p><div

style="text-indent:25px">圓柱滾子軸承屬于分離型軸承，圓柱滾子軸承安裝與拆卸非常方便。圓柱滾子軸承能承受較大的徑向負(fù)荷并適用于在高速運(yùn)轉(zhuǎn)場(chǎng)合下使用。此類軸承允許內(nèi)圈軸線與外圈軸線的角度誤差（傾斜度）很小，只有2′～4′。因此，對(duì)軸和軸承座的加工精度相對(duì)較高否則，容易在滾道接觸部位出現(xiàn)不均勻負(fù)荷或應(yīng)力集中。但對(duì)滾子或滾道接觸母線進(jìn)行修正后可以減少應(yīng)力集中情況的發(fā)生。圓柱滾子軸承根據(jù)裝用滾動(dòng)體的列數(shù)不同，可以分為單列、雙列和多列圓柱滾子軸承等不同結(jié)構(gòu)。不同結(jié)構(gòu)軸承還表現(xiàn)在擋邊的位置設(shè)計(jì)方面。大型軸承因不能用手旋轉(zhuǎn)，注意檢查滾動(dòng)體、滾道面、保持架、擋邊面等外觀。南通NN3013/W33雙列圓柱滾子系列軸承</p><p
