style="text-indent:25px">NNF型軸承是雙列滿裝圓柱滾子軸承，軸承由一個(gè)帶中擋邊外圈，兩個(gè)有雙擋邊內(nèi)圈的結(jié)構(gòu)型式。滾子由內(nèi)圈的擋邊引導(dǎo)，兩個(gè)內(nèi)圈用緊固圈固定在一起。該結(jié)構(gòu)除了可以承受很大的徑向載荷和軸向載荷之外，還可以承受傾覆力矩，因此，常用作固定端軸承使用。 NNF型軸承兩側(cè)采用接觸式密封。軸承內(nèi)填有潤(rùn)滑脂，潤(rùn)滑脂的工作溫度為-50℃至+110℃，但由于受密封材料的限制，軸承的工作溫度限于于-40℃至+80℃之間。在使用工況較好的情況下，帶有密封的NNF軸承無(wú)需進(jìn)行保養(yǎng)，若軸承長(zhǎng)期處于水汽或污染環(huán)境，且為中、高速運(yùn)轉(zhuǎn)時(shí)，可通過(guò)外圈上的潤(rùn)滑油槽和潤(rùn)滑油孔對(duì)軸承進(jìn)行補(bǔ)充潤(rùn)滑。圓柱滾子軸承需要注意哪些問(wèn)題？南昌NN3010K

①短防銹期包裝：防銹期3～6個(gè)月，適用于大批量發(fā)貨到同一訂戶，短期內(nèi)便投入使用的軸承。經(jīng)雙方協(xié)議，以方便使用為原則，采用簡(jiǎn)易包裝。 ②一般防銹期包裝：防銹期一年，適用于一般用途的軸承。 ③長(zhǎng)防銹期包裝：防銹期二年，適用于**和精密軸承。軸承內(nèi)包裝材料有聚乙烯塑料筒（盒）、牛皮紙、平紋和皺紋聚乙烯復(fù)合紙、紙盒、聚乙烯或聚乙烯塑料膜、尼龍緊固帶或塑料編制緊固帶、防水**度塑料帶、麻布袋等。以上材料均需保證材料的耐腐蝕性能試驗(yàn)合格。西寧81140雙列圓柱滾子系列軸承</p><p
