style="text-indent:25px">雙列圓柱滾子軸承清洗需要注意哪些方面？將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)剩余潤滑劑的量并對(duì)潤滑劑采樣，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)常過濾保持清潔。清洗后，立即在軸承上涂布防銹油或防銹脂。NN型結(jié)構(gòu):外圈無擋邊,內(nèi)圈有雙擋邊。西安81106雙列圓柱滾子系列軸承哪個(gè)廠家質(zhì)量好</p><p
