Uluhlu ngalunye lokuthwala luneempawu ezahlukeneyo ngenxa yoyilo lwalo olwahlukileyo, okwenza ukuba lufaneleke kuluhlu oluthile lwesicelo.Ngokomzekelo, iibhodi zebhola ze-groove ezinzulu ziyakwazi ukumelana ne-radial kunye nemithwalo ye-axial kunye ne-friction ephantsi, enokuvelisa ukuchaneka okuphezulu kunye neemveliso zengxolo ephantsi.Ke ngoko, zifanelekile kwizicelo zeemoto ezincinci okanye eziphakathi.Iibheringi ze-roller ezizii-Spherical zinokumelana nemithwalo enzima kakhulu, kwaye inokuzilungisa ngokuzenzekelayo.Ezi mpawu zenza ukuba zilungele izicelo zobunjineli, kuba kwezi zicelo umthwalo unzima kakhulu, kunye ne-deformation kunye nokungahambi kakuhle okubangelwa ngumthwalo onzima.

Nangona kunjalo, xa ukhetha iibheringi, kudla ngokufuneka ukuba kuqwalaselwe izinto ezahlukeneyo ukulinganisa ubunzima babo, ngoko ke akukho "umgaqo jikelele".

Ezinye iimpawu azixhomekekanga nje kuhlobo lokuthwala.Ngokomzekelo, ukucwangciswa okubandakanya i-angular contact ball bearing okanye i-tapered roller bear, ukuqina kwayo kuxhomekeke ekulayisheni kwangaphambili okukhethiweyo;umzekelo, umda wesantya sokuthwala ugqitywe yimiba efana nokuchaneka kokuchaneka, iindawo ezijikelezileyo zokuthwala, kunye noyilo lwekheji olugqitywe.

Kwiibheringi ze-cylindrical roller, uyilo lwamva nje lunomthamo omkhulu we-axial umthwalo kunezoyilo zendabuko.Nangona kunjalo, ngaphandle kwezi ntsilelo, kusenokunceda ukukhetha iibheringi.Ukongezelela, kufuneka siphinde sibone ukuba ukhetho lweebheringi lukwachatshazelwa yindleko epheleleyo yoqwalaselo olukhethiweyo olukhethiweyo kunye nokufumaneka kweemarike.

Xa uyila ulungelelwaniso lokuthwala, kufuneka linikele ingqalelo kumanqaku alo aphambili, njengokuthwala umthwalo kunye nokuthwala ubomi, ukungquzulana, isantya somda, ukukhutshwa kwangaphakathi okanye ukulayishwa kwangaphambili kokuthwala, ukuthambisa, ukutywinwa, njl. idatha efanelekileyo yale modeli.
