圓錐滾子軸承為分離型軸承、帶滾子和保持架的內(nèi)圈構(gòu)成內(nèi)組件，能與外圈分開(kāi)安裝。軸承內(nèi)、外圈具有錐形滾道，滾道之間裝有錐形滾子。圓錐滾子軸承主要用于承受以徑向負(fù)荷為主的徑向、軸向聯(lián)合負(fù)荷。軸承的軸向承載能力由接觸角α即外圈滾道角度決定，α越大，軸向承載能力越大。
單列圓錐滾子軸承：此種軸承只能***軸或外殼的一個(gè)方向的軸向位移，承受一個(gè)方向的軸向載荷。當(dāng)軸承承受徑向負(fù)荷時(shí)，將會(huì)產(chǎn)生一個(gè)軸向分力，所以常需要用另一個(gè)可承受反方向軸向力的軸承來(lái)加以平衡。
圓錐滾子軸承多采用鋼板沖壓保持架，但可根據(jù)用戶的需要及特大型軸承則采用滾子有支柱孔的支柱焊接結(jié)構(gòu)的保持架。為了防止軸承在高速運(yùn)轉(zhuǎn)時(shí)因離心力的作用在滾子與滾道間產(chǎn)生有害的滑移現(xiàn)象，軸承必須承受一定的***小徑向負(fù)荷，其值可向本司技術(shù)部門(mén)咨詢。
