style="text-indent:25px">內(nèi)圈或者外圈無擋邊的圓柱滾子軸承，其內(nèi)圈和外圈可以向軸向作相對移動，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)的套圈有單個擋邊的圓柱滾子軸承，可以承受一定程度的一個方向軸向負(fù)荷。一般使用鋼板沖壓保持架，或銅合金車制實體保持架。但也有一部分使用聚酰胺成形保持架。圓柱滾子軸承特點：1.滾子與滾道為線接觸或修下線接觸，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，能適應(yīng)因熱膨脹或安裝誤差引起的軸與外殼相對位置的變化，可作自由端支承使用。4.對軸或座孔的加工要求較高，軸承安裝后外圈軸線相對偏斜要嚴(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。上海好用的81102雙列圓柱滾子系列軸承雙列圓柱滾子軸承直徑與寬度之比一般在4~7之間。</p><div

style="text-indent:25px">辨別雙列圓柱滾子設(shè)備軸承的質(zhì)量，我們可以從以下幾個方面進(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。</p><p style="text-indent:25px">雙列圓柱滾子軸承的密封可分為自帶密封和外加密封兩類。所謂軸承自帶密封就是把軸承本身制造成具有密封性能裝置的。如軸承帶防塵蓋、密封圈等。這種密封占用空間很小，安裝拆卸方便，造價也比較低。所謂軸承外加密封性能裝置，就是在安裝端蓋等內(nèi)部制造成具有各種性能的密封裝置。對軸承外加密封的選擇應(yīng)考慮下列幾種主要因素： 1．軸承潤滑劑和種類（潤滑脂和潤滑油）； 2．軸承的工作環(huán)境，占用空間的大?。?3．軸的支承結(jié)構(gòu)優(yōu)點，允許角度偏差； 4．密封表面的圓周速度； 5．軸承的工作溫度； 6.制造成本。根據(jù)軸承工作狀況和工作環(huán)境對密封程度的要求，在工程設(shè)計上常常是綜合運用各種密封形式，以達(dá)到更好的密封效果。軸承的工作間隱或予載荷取決于轉(zhuǎn)速、負(fù)載、潤滑、剛度、溫及軸承座的精度。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">為使雙列圓柱軸承充分發(fā)揮并長期保持其應(yīng)有的性能，必須切實做好定期維護(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。但長期存放時，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，保管場所應(yīng)避開直射陽光或與寒冷的墻壁觸。上海好用的81102雙列圓柱滾子系列軸承</p><p
