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荷并適用于在高速運轉(zhuǎn)場合下使用。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，對軸和軸承座的加工精度相對較高否則，容易在滾道接觸部位出現(xiàn)不均勻負荷或應力集中。但對滾子或滾道接觸母線進行修正后可以減少應力集中情況的發(fā)生。圓柱滾子軸承根據(jù)裝用滾動體的列數(shù)不同，可以分為單列，呼和浩特NN3013K/W33雙列圓柱滾子系列軸承供應，呼和浩特NN3013K/W33雙列圓柱滾子系列軸承供應、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)在擋邊的位置設計方面。為了判斷拆下的圓柱滾子軸承能否重新使用，呼和浩特NN3013K/W33雙列圓柱滾子系列軸承供應，需要重先檢查其尺寸精度、旋轉(zhuǎn)精度。呼和浩特NN3013K/W33雙列圓柱滾子系列軸承供應</p><div

style="text-indent:25px">圓錐孔雙列圓柱滾子軸承屬于線性接觸軸承,它承載能力和剛度高于點接觸的角接觸軸承，常用于載荷較大、要求剛度較高，而轉(zhuǎn)速相對來說不很高的中、大、重型機床主軸系統(tǒng)中。雙列圓柱滾子軸承直徑與寬度之比一般在4~7之間，由于雙列圓柱滾子軸承的徑寬比較大，導致在主軸箱孔中和主軸上安裝時的導向性能較差。再者大型機床零件尺寸和質(zhì)量較大，給裝配工作帶來一定的難度，容易造成安裝軸承時的力量不均勻。以上的種種原因，導致主軸軸承的內(nèi)外圈安裝位置偏移,軸承滾動體與軸承的內(nèi)外圈接觸不良，致使主軸剛度和回轉(zhuǎn)精度降低。檢驗主軸軸承的內(nèi)外圈安裝端正的方法如下:在預緊軸承內(nèi)圈的過程中，不斷的轉(zhuǎn)動主軸，同時觀察軸承滾動體的轉(zhuǎn)動情況。</p><p style="text-indent:25px">雙列圓柱滾子軸承的潤滑分為：脂潤滑和油潤滑。為了使軸承很好地發(fā)揮機能，首先，要選擇適合使用條件、使用目的的潤滑方法。若只考慮潤滑，油潤滑的潤滑性占優(yōu)勢。但是，脂潤滑有可以簡化軸承周圍結(jié)構(gòu)的特長，將脂潤滑和油潤滑的利弊比較。軸承壽命在一定載荷作用下，軸承在出現(xiàn)點蝕前所經(jīng)歷的轉(zhuǎn)數(shù)或小時數(shù)，稱為軸承壽命。滾動軸承之壽命以轉(zhuǎn)數(shù)（或以一定轉(zhuǎn)速下的工作的小時數(shù)）定義：在此壽命以內(nèi)的軸承，應在其任何軸承圈或滾動體上發(fā)生初步疲勞損壞（剝落或缺損）。然而無論在實驗室試驗或在實際使用中，都可明顯的看到，在同樣的工作條件下的外觀相同軸承，實際壽命大不相同。此外還有數(shù)種不同定義的軸承“壽命”，其中之一即所謂的“工作壽命”，它表示某一軸承在損壞之前可達到的實際壽命是由磨損、損壞通常并非由疲勞所致，而是由磨損、腐蝕、密封損壞等原因造成。圓柱滾子軸承特點：可作自由端支承使用。</p><div
