style="text-indent:25px">深溝球軸承，運轉(zhuǎn)中軸承載荷過小，會使球與滾道之間產(chǎn)生滑動，成為擦傷的起因。特別是球和保持架重量大的大型深溝球軸承有這種傾向。在很多情況下，軸承會發(fā)生銹蝕現(xiàn)象，導(dǎo)致軸承銹蝕的原因有很多，我們?nèi)粘Ｉ钪休^常見的主要有以下幾種因素：1）由于密封裝置不良，被水分、污物等侵入；2）軸承長期不用，超過防銹期，缺乏維護保養(yǎng)。3）金屬表面粗糙度較大；4）接觸有腐蝕的化學(xué)介質(zhì)，浙江角接觸球軸承哪家好，軸承清洗不干凈，表面有污物沾附，或用汗手接觸軸承，軸承清洗后，浙江角接觸球軸承哪家好，未及時包裝或安裝，長期暴露與空氣中，浙江角接觸球軸承哪家好，受到空氣水分的侵襲和沾染；5）環(huán)境溫度和濕度和接觸各種環(huán)境介質(zhì)；防銹劑失效或質(zhì)量不符要求。直線軸承是一種直線運動系統(tǒng)，用于直線行程與圓柱軸配合使用。浙江角接觸球軸承哪家好</p><div
