style="text-indent:25px">軸承(Bearing)是當(dāng)代機械設(shè)備中一種重要零部件。它的主要功能是支撐機械旋轉(zhuǎn)體，降低其運動過程中的摩擦系數(shù)，并保證其回轉(zhuǎn)精度。按運動元件摩擦性質(zhì)的不同，軸承可分為滾動軸承和滑動軸承兩大類。其中滾動軸承已經(jīng)標(biāo)準(zhǔn)化、系列化，但與滑動軸承相比它的徑向尺寸、振動和噪聲較大，價格也較高。滾動軸承一般由外圈、內(nèi)圈、滾動體和保持架四部分組成。按滾動體的形狀，滾動軸承分為球軸承和滾子軸承兩大類。無錫哈配機電設(shè)備有限公司致力于為客戶打造生態(tài)化互聯(lián)網(wǎng)平臺，為客戶提供一站式整體解決方案。作為我們擁有充足的軸承備貨，且具備專業(yè)的管理、技術(shù)、銷售精英團(tuán)隊，售后服務(wù)體系完善，為我國機床行業(yè)智能化貢獻(xiàn)力量！NN3010K

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(shè)計和NN設(shè)計。NN型設(shè)計內(nèi)圈雙擋邊而外圈無擋邊。NNU型設(shè)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。</p><p style="text-indent:25px">辨別雙列圓柱滾子設(shè)備軸承的質(zhì)量，我們通常從以下幾個方面進(jìn)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(chǎn)的品牌都有自己專門的設(shè)計人員對外包裝進(jìn)行設(shè)計，并且安排生產(chǎn)條件過關(guān)的工廠進(jìn)行制作生產(chǎn)，因此，產(chǎn)品的包裝無論從線條到色塊都應(yīng)該是非常清晰，毫不含糊。鋼印字是否清晰：每一個軸承產(chǎn)品都會在軸承產(chǎn)品體上印有其品牌字樣、標(biāo)號等。雖然字體非常小，但是正規(guī)廠家生產(chǎn)的產(chǎn)品都采用了鋼印技術(shù)印字，而且在未經(jīng)過熱處理之前就進(jìn)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(chǎn)品的字體非但模糊，由于印字技術(shù)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(yán)重。圓柱滾子軸承內(nèi)部結(jié)構(gòu)采用滾子呈平行排列，滾子之間裝有間隔保持器或者隔離塊。</p><div

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(dāng)代機械重要零件，應(yīng)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(yīng)有很好的耐磨性能。 2. 接觸疲勞強度：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度。雙列圓柱滾子軸承（高剛性系列）采用新材料和新設(shè)計，可提高機床的性能。NN3010K /W33雙列圓柱滾子系列軸承供應(yīng)商</p><p
