Ib-kab sib sib zog nqus groove pob bearings nyob hauv cov qauv ntawm txhua lub nplhaib muaj qhov sib tshooj ntawm ob qhov ncaj nruab nrab ntawm lub pob yog kwv yees li ib feem peb ntawm kev ua ntu zus ntev. Kev sib sib zog nqus groove pob kabmob yog tsuas yog siv los tiv thaiv radial load, nws tuaj yeem tiv taus qee yam ntawm axial load. Thaum cov kabmob radial tshem tawm nce ntxiv, nrog rau qhov xwm ntawm lub kaum lub pob hu rau lub pob bearings tuaj yeem tiv taus ob qho kev qhia hloov axial load. Nrog rau qhov loj me me piv rau lwm hom bearings, xws li cov txhuam kev sib txhuam coefficient yog me me, tsis tshua muaj siab nrawm, siab meej, thaum cov neeg siv xaiv ntawm cov nyiam cov hom. Feem ntau ntawm cov qhov tob hauv pob npoo pob yog tsim los ntawm Inner lub nplhaib, Cov nplhaib sab nraud, Cov ntaub thaiv av lossis cov ntsaws ruaj ruaj rau roj hmab, Kab tawb, Hlau pob.Lubricant thiab gasket.
