          沖壓外圈滾針軸承

           

          □ 產品介紹

          沖壓外圈滾針軸承
          Drawn Cup Needle Roller Bearings 沖壓外圈滾針軸承
          沖壓外圈滾針軸承BK2018-RS是我司傳統產品,BK2018-RS此軸承的外圈是用薄鋼板精密沖壓成形的,結構空間小,且具有較大負荷容量。適用于安裝空間受到限制和殼體孔不宜作為滾道的場合。且壓入軸承座孔后不必進一步軸向定位。

            合适的内圈

          壓外圈滾針軸承是用ST14鋼板精密沖壓而成形并經高溫碳氮共滲處理,其特點是剖面高度極小,且具有極強載荷容量,采用高剛性保持架引導G2級滾針線狀外圈滾道,使其更好地平行于軸線.

            該類滾針軸承的外圈與軸承箱采用靜配合,不需要軸向固定裝置。即使在高速大負荷條件下,也能充分保持軸承功能。另外,因貯脂容積大,可長期不加潤滑脂,也能保證滾針軸承長期靈活旋轉,設備運轉流暢.

          1.These load, speed and mass is reference of choice only.            
          2.If the cages are made of plastics, suffix "TN" is added to the bearing No.,the maximum allowable     
            working themperrature is 120℃ in continuous working and 180℃ in short working.          
          3.With grease lubrication, 60% of these limiting speed will apply.
