Ibhereyitha yebhola eqhelekileyo iqulathe iindlela zomdyarho zangaphakathi nezangaphandle, inani lezinto ezingqukuva ezahlulwe yisithwali, kwaye, rhoqo, izikhuselo kunye/okanye izitywina ezenzelwe ukugcina ukungcola kungangeni kwaye kufakwe igrisi. Xa ifakiwe, umdyarho wangaphakathi udla ngokucinezelwa kancinci kwishafti kwaye umdyarho wangaphandle ubanjwe endlwini. Uyilo luyafumaneka lokuphatha imithwalo yeradial ecocekileyo, imithwalo ye-axial ecocekileyo (i-thrust), kunye nemithwalo yeradial edibeneyo kunye ne-axial.

Iibheringi zebhola zichazwa njengezinonxibelelwano lwenqaku; oko kukuthi, ibhola nganye iqhagamshelana nomdyarho kwindawo encinci kakhulu - inqaku, ngokwethiyori. Iibheringi zenzelwe ukuba ukuguquguquka okuncinci okwenziwa yibhola njengoko ijikeleza ingena kwaye iphuma kwindawo yomthwalo kungadluli kwinqanaba lemveliso; ibhola engathululwanga ibuyela kwimo yayo yokuqala. Iibheringi zebhola azinabomi bungenasiphelo. Ekugqibeleni, ziyasilela ngenxa yokudinwa, ukuqhekeka, okanye naziphi na ezinye izizathu. Zenziwe ngokwezibalo ezinobomi obuluncedo apho inani elithile kulindeleke ukuba lisilele emva kwenani elithile leenguqu.

Abavelisi banikezela ngeebheringi zeradial zomqolo omnye kwiindidi ezine kuluhlu lwee-bore sizes ezisemgangathweni. Iibheringi ze-angular contact zenzelwe ukumelana nomthwalo we-axial kwicala elinye kwaye zinokuphindwe kabini ukuze ziphathe umthwalo we-thrust kwiindlela ezimbini.

Ukulungelelaniswa kweshaft kunye neebhereyitha kudlala indima ebalulekileyo ebomini bokuthwala. Ukuze kubekho amandla aphezulu okungahambisani, kusetyenziswa iibhereyitha ezizilungelelanisayo.

Ukwandisa umthamo womthwalo we-radial, i-bearing carrier iyasuswa kwaye isithuba esiphakathi kwemidyarho sizaliswa ziibhola ezininzi kangangoko ziya kufaneleka—oko kubizwa ngokuba yi-full-complement bearing. Ukuguguleka kwezi bearing kuphezulu kunezo zisebenzisa i-carriers ngenxa yokukhuhlana phakathi kwezinto eziqengqelekayo ezikufutshane.
Kwizicelo ezibalulekileyo apho ukuchitheka kweshaft kuyinto exhalabisayo—umzekelo, iispindle zezixhobo zomatshini—iibheringi zinokulayishwa kwangaphambili ukuze zithathe naluphi na ucango kwindibano yeebheringi esele inyamezelekile.
