Sib sib zog nqus groove pob bearings yog cov feem ntau siv dov bearings. Nws cov qauv yog yooj yim thiab siv tau yooj yim. Nws yog tsuas yog siv los dais radial load, tab sis thaum lub radial clearance ntawm cov kabmob yog nce, nws muaj ib tug tej yam kev ua tau zoo ntawm angular hu pob bearings thiab yuav dais radial thiab axial ua ke loads. Thaum qhov ceev yog siab thiab thrust pob bearings tsis haum, lawv tuaj yeem siv los dais cov axial ntshiab. Piv nrog rau lwm hom bearings ntawm tib qhov loj li sib sib zog nqus groove pob bearings, cov bearings muaj ib tug me me coefficient ntawm kev sib txhuam thiab ib tug siab limiting ceev. Txawm li cas los xij, nws tsis tiv taus qhov cuam tshuam thiab tsis haum rau cov khoom hnyav.
Sib sib zog nqus groove pob bearings mounted ntawm lub ncej tuaj yeem txwv qhov kev hloov pauv ntawm axial nyob rau hauv ob qho tib si kev taw qhia ntawm lub ncej los yog vaj tse nyob rau hauv lub axial clearance ntau yam ntawm cov kabmob, yog li lawv tuaj yeem muab tso rau hauv axial ntawm ob qho tib si. Tsis tas li ntawd, hom kabmob no kuj muaj peev xwm sib dhos, thaum qaij 2 '~ 10' txheeb ze rau lub tsev bore, nws tseem tuaj yeem ua haujlwm ib txwm, tab sis nws muaj qee yam cuam tshuam rau kev coj tus kheej lub neej.
