I-Cylindrical roller bearing ngaphandle kwendandatho yangaphakathi Uchungechunge lomugqa owodwa: I-RNU, i-RNU uchungechunge lwamabheringi angama-cylindrical roller asekelwe kumklamo we-NU wamabheringi angama-cylindrical roller futhi ahlinzekwa ngaphandle kwendandatho yangaphakathi.Lawa ma-bearings asetshenziswa ngokujwayelekile lapho kwenziwa khona imigwaqo eqinile nephansi ku-shaft.Ngenxa yokuthi amabheringi e-RNU awanayo indandatho yangaphakathi, ububanzi be-shaft bungaba bukhulu ukuze buhlinzeke ngohlelo oluqinile, oluqinile.Ukwengeza, ukufuduka kwe-axial okungenzeka kwe-shaft okuhlobene nezindlu kunqunyelwe kuphela umzila womjaho ku-shaft.
