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：表面是否有渾濁的油跡：表面是否有渾濁的油跡這需要我們在購買進(jìn)口軸承時應(yīng)該特別注意。由于國內(nèi)的防銹技術(shù)與國外先進(jìn)制造國還有一定的差距，因此對軸承體進(jìn)行防銹處理時很容易留下厚厚的油跡，用手接觸時感覺粘粘稠稠的，而國外原裝進(jìn)口的軸承上幾乎看不到任何防銹油的痕跡。據(jù)業(yè)內(nèi)人士介紹，沈陽NN3013/W33雙列圓柱滾子系列軸承造價，特別細(xì)心的人可以在進(jìn)口軸承上聞到一種特殊的味道，這就是防銹油的味道。倒角是否均勻：所謂軸承的倒角，也就是橫面與豎面的交接處，沈陽NN3013/W33雙列圓柱滾子系列軸承造價，仿冒的軸承產(chǎn)品由于生產(chǎn)技術(shù)的限制，在這些邊邊角角的部位處理得不盡人意，沈陽NN3013/W33雙列圓柱滾子系列軸承造價，這一點我們可以輕松辨別NNU型結(jié)構(gòu):內(nèi)圈無擋邊，外圈有雙擋邊。沈陽NN3013/W33雙列圓柱滾子系列軸承造價</p><div

style="text-indent:25px">圓柱滾子軸承的滾動體一般采用圓柱滾子在單一的滾道上十字交叉相互排列，滾子與滾子之間通過保持器或者隔離塊間隔，其具有較高的旋轉(zhuǎn)精度，較大的承載能力、較小的外形尺寸及較高的旋轉(zhuǎn)速度和剛性，具有很普遍的用途及其他軸承無法比擬的優(yōu)越性。圓柱滾子軸承安裝使用： 1.該軸承為分離型，用戶安裝時可根據(jù)需要自行調(diào)整游隙。 2.軸承在使用前，應(yīng)用汽油或煤油清洗干凈，并保持良好潤滑。 3.軸承安裝時，應(yīng)將軸承壓入部件內(nèi)，嚴(yán)禁敲打。 4.軸承存放處應(yīng)清潔通風(fēng)，避免潮濕，需長期保管的軸承，應(yīng)定期防銹。南通NNU4922K/W33雙列圓柱滾子系列軸承高精度圓柱滾子軸承可應(yīng)用于機(jī)床主軸或徑向負(fù)荷較重、剛性要求較高的主軸上。</p><div style="width:100%;text-align: center;"><img style="max-width:

(5)原因:裝配質(zhì)量低方法:提高裝配質(zhì)量。 (6)原因:軸承內(nèi)外殼跑圈方法：更換軸承及相關(guān)磨損部件。 (7)軸向力太大方法：清洗、調(diào)正密封口環(huán)間隙要求 0.2～0.3mm 之間,更正葉輪平衡孔直徑及校驗靜平衡值。
