    光滑

    滾動軸承的光滑目有減少軸承內部衝突及磨損
，避免燒粘；延伸其運用壽數；排出衝突熱
、冷卻
，避免軸承過熱，避免光滑油自身老化；也有避免異物侵入軸承內部，或避免生鏽、腐蝕之效果。

    光滑方法

    軸承的光滑方法，分為脂光滑和油光滑。為了使軸承很好地發揮機能，首要，要挑選合適運用條件、運(yun)用(yong)目(mu)的(de)的(de)光(guang)滑(hua)方(fang)法(fa)。若(ruo)隻(zhi)考(kao)慮(lv)光(guang)滑(hua)
，油(you)光(guang)滑(hua)的(de)光(guang)滑(hua)性(xing)占(zhan)優(you)勢(shi)。但(dan)是(shi)，脂(zhi)光(guang)滑(hua)有(you)能(neng)夠(gou)簡(jian)化(hua)軸(zhou)承(cheng)周(zhou)圍(wei)結(jie)構(gou)的(de)專(zhuan)長(chang)
，將(jiang)脂(zhi)光(guang)滑(hua)和(he)油(you)光(guang)滑(hua)的(de)利(li)害(hai)比(bi)較(jiao)。光(guang)滑(hua)時(shi)要(yao)特(te)別(bie)注(zhu)意(yi)用(yong)量(liang)，不(bu)管(guan)是(shi)油(you)光(guang)滑(hua)仍(reng)是(shi)脂(zhi)光(guang)滑(hua)，量(liang)太(tai)少(shao)光(guang)滑(hua)不(bu)充(chong)分(fen)影(ying)響(xiang)軸(zhou)承(cheng)壽(shou)數(shu)，量(liang)太(tai)多(duo)會(hui)發(fa)生(sheng)大(da)的(de)阻(zu)力(li)，影(ying)響(xiang)轉(zhuan)速(su)。

    密封

    軸承的密封可分為自帶密封和外加密封兩類。所謂軸承自帶密封便是把軸承自身製作成具有密封功能裝置的。如軸承帶防塵蓋、密mi封feng圈quan等deng。這zhe種zhong密mi封feng占zhan用yong空kong間jian很hen小xiao，裝zhuang置zhi拆chai開kai方fang便bian

，造zao價jia也ye比bi較jiao低di。所suo謂wei軸zhou承cheng外wai加jia密mi封feng功gong能neng裝zhuang置zhi，便bian是shi在zai裝zhuang置zhi端duan蓋gai等deng內nei部bu製zhi作zuo成cheng具ju有you各ge種zhong功gong能neng的de密mi封feng裝zhuang置zhi。軸zhou承cheng外wai加jia密mi封feng又you分fen為wei非fei觸chu摸mo式shi密mi封feng與yu觸chu摸mo式shi密mi封feng兩liang種zhong。其qi中zhong非fei觸chu摸mo式shi密mi封feng適shi用yong於yu高gao速su和he高gao溫wen場chang合he，有you空kong隙xi式shi
、迷宮式和墊圈式等不同結構方式。觸摸式密封適用於中、低速的工作條件
，常用的有毛氈密封、皮碗密封等結構方式。
