style="text-indent:25px">雙列圓柱滾子軸承的潤(rùn)滑分為脂潤(rùn)滑和油潤(rùn)滑。為了使軸承很好地發(fā)揮機(jī)能，首先，要選擇適合使用條件、使用目的的潤(rùn)滑方法。若只考慮潤(rùn)滑，油潤(rùn)滑的潤(rùn)滑性占優(yōu)勢(shì)。但是，脂潤(rùn)滑有可以簡(jiǎn)化軸承周圍結(jié)構(gòu)的特長(zhǎng)，將脂潤(rùn)滑和油潤(rùn)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(diǎn)蝕前所經(jīng)歷的轉(zhuǎn)數(shù)或小時(shí)數(shù)，稱為軸承壽命。滾動(dòng)軸承之壽命以轉(zhuǎn)數(shù)（或以一定轉(zhuǎn)速下的工作的小時(shí)數(shù)）定義：在此壽命以內(nèi)的軸承，應(yīng)在其任何軸承圈或滾動(dòng)體上發(fā)生初步疲勞損壞（剝落或缺損）。然而無論在實(shí)驗(yàn)室試驗(yàn)或在實(shí)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(shí)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(dá)到的實(shí)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。</p><p style="text-indent:25px">為使雙列圓柱軸承充分發(fā)揮并長(zhǎng)期保持其應(yīng)有的性能，必須要切實(shí)做好定期維護(hù)保養(yǎng)(定期檢查)。通過適當(dāng)?shù)亩ㄆ跈z查，做到早期發(fā)現(xiàn)故障，防止事故于未然，對(duì)提高生產(chǎn)率和經(jīng)濟(jì)性十分重要。一般雙列圓柱滾子軸承在出廠時(shí)均涂有適量的防銹油并用防銹紙包裝，只要該包裝不被破壞，軸承的質(zhì)量將得到保證。但長(zhǎng)期存放時(shí)，擬在濕度低于65%、溫度為20℃左右的條件下，存放在高于地面30cm的架子上為宜。另外，保管場(chǎng)所應(yīng)避開直射陽光或與寒冷的墻壁觸。雙列圓柱滾子軸承使用時(shí)有哪些需要注意的地方？</p><div

style="text-indent:25px">為了判斷拆下的圓柱滾子軸承能否重新使用，要著重檢查其尺寸精度、旋轉(zhuǎn)精度、內(nèi)部游隙以及配合面、滾道面、保持架和密封圈等。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，軸承的重要性愈高愈須慎重檢查。關(guān)于檢查結(jié)果，可由用慣軸承或精通軸承者進(jìn)行判斷。判斷的標(biāo)準(zhǔn)根據(jù)機(jī)械性能和重要度以及檢查周期等而有所不同。如有以下?lián)p傷，軸承不得重新使用，必須更換。 1) 軸承零部件的斷裂和缺陷。 2) 滾道面物滾動(dòng)面的剝離。高精度圓柱滾子軸承截面小，承載能力高，變形小。連云港NNU4922KTN/W33雙列圓柱滾子系列軸承</p><p style="text-indent:25px">C1一直以來較為被采用游隙。NNU4926K/W33雙列圓柱滾子系列軸承哪家比較好</p><p
