Muaj qhov sib txawv tseem ceeb hauv cov khoom siv raw, cov qauv thiab kev siv ntawm cov hlau bearings thiab steel bearings. Hlau bearings feem ntau yog ua los ntawm tooj liab, hlau, txhuas thiab lwm yam ntaub ntawv hlau. Lawv muaj cov qauv yooj yim thiab tsim nyog rau kev siv cov khoom siv tshuab feem ntau. Lawv yog cov yooj yim los tsim thiab tsis tshua muaj nqi. Cov kabmob steel feem ntau yog siv cov hlau muaj zog, uas tuaj yeem tiv taus ntau dua thiab kev vibrations thiab tsim nyog rau cov chaw tshwj xeeb uas yuav tsum tau muaj zog dua thiab muaj peev xwm thauj khoom.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, hlau bearings yog haum rau kev siv dav siv vim lawv cov qauv yooj yim thiab tus nqi qis. Vim lawv lub zog siab thiab ua haujlwm ntev, steel bearings yog tsim rau siv nyob rau hauv ib puag ncig hnyav thiab tuaj yeem tiv taus ntau dua thiab kev vibrations. Kev xaiv cov bearings tsim nyog yuav tsum tau txiav txim siab raws li kev xav tau ntawm cov cuab yeej siv kho tshuab tshwj xeeb, uas yuav tsum tsis yog tsuas yog ua tau raws li qhov yuav tsum tau ua, tab sis kuj xav txog tus nqi thiab kav ntev.
