style="text-indent:25px">內(nèi)圈或者外圈無(wú)擋邊的圓柱滾子軸承，其內(nèi)圈和外圈可以向軸向作相對(duì)移動(dòng)，所以可以作為自由端軸承使用。在內(nèi)圈和外圈的某一側(cè)有雙擋邊，另一側(cè)的套圈有單個(gè)擋邊的圓柱滾子軸承，可以承受一定程度的一個(gè)方向軸向負(fù)荷。一般使用鋼板沖壓保持架，或銅合金車(chē)制實(shí)體保持架。但也有一部分使用聚酰胺成形保持架。圓柱滾子軸承特點(diǎn)：1.滾子與滾道為線(xiàn)接觸或修下線(xiàn)接觸，徑向承載能力大，適用于承受重負(fù)荷與沖擊負(fù)荷。2.摩擦系數(shù)小，適合高速，極限轉(zhuǎn)速接近深溝球軸承。3.N型及NU型可軸向移動(dòng)，能適應(yīng)因熱膨脹或安裝誤差引起的軸與外殼相對(duì)位置的變化，可作自由端支承使用。4.對(duì)軸或座孔的加工要求較高，軸承安裝后外圈軸線(xiàn)相對(duì)偏斜要嚴(yán)加控制，以免造成接觸應(yīng)力集中。5.內(nèi)圈或外圈可分離，便于安裝和拆卸。雙列圓柱滾子軸承潤(rùn)滑的目的是：減少摩擦及磨損在構(gòu)成軸承的套圈、滾動(dòng)體及保持器的相互接觸部分。NN3019/W33雙列圓柱滾子系列軸承品牌</p><p style="text-indent:25px">雙列圓柱滾子軸承潤(rùn)滑的目的是：排出摩擦熱、冷卻循環(huán)給油法等可以用油排出由摩擦發(fā)生的熱。NN3019/W33雙列圓柱滾子系列軸承品牌</p><p style="text-indent:25px">當(dāng)對(duì)雙列圓柱滾子軸承拆下檢查時(shí)，先用攝影等方法做好外觀記錄。另外，要確認(rèn)剩余潤(rùn)滑劑的量并對(duì)潤(rùn)滑劑采樣，然后再清洗軸承。a、軸承的清洗分粗洗和精洗進(jìn)行，并可在使用的容器底部放上金屬網(wǎng)架。b、粗洗時(shí)，在油中用刷子等清掃潤(rùn)滑脂或粘著物。此時(shí)若在油中轉(zhuǎn)動(dòng)軸承，注意會(huì)因異物等損傷滾動(dòng)面。c、精洗時(shí)，在油中慢慢轉(zhuǎn)動(dòng)軸承，須仔細(xì)地進(jìn)行。通常使用的清洗劑為中性不含水柴油或煤油，根據(jù)需要有時(shí)也使用溫性堿液等。不論用哪種清洗劑，都要經(jīng)常過(guò)濾保持清潔。清洗后，立即在軸承上涂布防銹油或防銹脂。NN3019/W33雙列圓柱滾子系列軸承品牌</p></p><br
