Cov kabmob kheej kheej muaj ib lub nplhaib sab hauv nrog ob txoj kab sib tw uas tig mus rau lub axis ntawm cov kabmob, ib lub nplhaib sab nraud nrog ib txoj kab sib tw kheej kheej, cov menyuam kheej kheej, cov tawb thiab, hauv qee qhov kev tsim, kuj muaj cov nplhaib qhia sab hauv lossis cov nplhaib nruab nrab. Cov kabmob no kuj tuaj yeem kaw tau. Feem ntau cov kabmob kheej kheej yog tsim los nrog ob kab ntawm cov menyuam, uas tso cai rau lawv nqa cov khoom hnyav radial thiab cov khoom hnyav axial. Kuj tseem muaj cov qauv tsim nrog ib kab ntawm cov menyuam, tsim nyog rau cov khoom hnyav radial qis dua thiab yuav luag tsis muaj cov khoom hnyav axial.
Cov kabmob ntawm lub tshuab ntawv yog cov khoom siv ntawm lub tshuab ntawv.
Cov kabmob tshuab ntawv, uas yog cov kabmob uas muaj cov roj nplua nyeem tshwj xeeb uas muab cov roj nplua nyeem tas mus li rau kev ua kom lubrication ntev.
Cov spherical roller bearings dominate tus qauv tsim, tshwj xeeb tshaj yog thaum xaiv cov bearings loj thiab nruab nrab.
