style="text-indent:25px">選擇軸承時，主要考慮因素如下：軸承的載荷：軸承所受載荷的大小、方向和性質(zhì)是選擇軸承的主要因素。根據(jù)載荷的大小選擇軸承時，相比于球軸承的點接觸，滾子軸承中的主要元件間是線接觸，易用于承受的載荷，承載后的變形也小。根據(jù)載荷方向選擇軸承時，對于純軸向載荷，一般選擇推力軸承。較大的軸向力選擇推力滾子軸承。較小的軸向力選擇推力球軸承。對于純徑向載荷，一般選用深溝球軸承、圓柱滾子軸承或滾針軸承。當在承受徑向載荷的同時，還承受不大的軸向載荷時，可選擇深溝球軸承或圓錐滾子軸承；當軸向載荷較大的時候，可選用接觸角較大的角接觸球軸承或圓錐滾子軸承。河北轉(zhuǎn)盤軸承廠商不銹鋼軸承衛(wèi)生：不銹鋼自然干凈，不腐蝕。</p><div
