Iibheringi zezinye zezona zinto zibalulekileyo kwiimveliso zeemoto. Iimeko zokusebenza ezikhethekileyo zibeka iimfuno eziphezulu kakhulu kwiibheringi ngokwazo kunye nokuthambisa kwazo. Umzekelo, iindawo ezinobushushu obuphezulu, iindawo ezinobushushu obuphantsi, ukuguquguquka okukhulu kobushushu, kunye neendawo ezineenkalo zongcoliseko zonke zibonelela ngeemeko ezikhethekileyo ezifuna ukukhethwa ngononophelo kweebheringi. Abanye abavelisi beebheringi baphuhlise iibheringi zeenjongo ezikhethekileyo ezifanelekileyo kwezi meko. Olu lulwazi olubalulekileyo ekufuneka abayili beemoto baluqonde kwaye baluqonde ukuze bathintele ukungathembeki kweemoto okubangelwa kukukhethwa kweebheringi ngendlela engafanelekanga.
Iibheringi zebhola ezinzulu ezifanelekileyo kumaqondo obushushu aphezulu naphantsi zenziwe ngendlela efanayo neebheringi zebhola ezinzulu ezisemgangathweni. Ezi bheringi zixhotyiswe ngoyilo olunesithuba sokulayisha ibhola, esikwaziyo ukumelana nemithwalo ephakathi yeradial kunye nemithwalo ye-axial kuzo zombini iindlela. Zinendawo enkulu yokungena ngaphakathi kwaye zifakelwe iikheyiji ezikhethekileyo. Uluhlu lokungena kweebheringi zebhola ezinzulu ezishushu kakhulu luphindwe kane kune-C5 clearance, nto leyo ethintela iibheringi ukuba zingabambeki ngexesha lokupholisa ngokukhawuleza. Imiphezulu yeebheringi kunye neengubo zothuli ziphathwa nge-manganese phosphating ukuthintela ukugqwala kunye nokuphucula ukusebenza. Kwiibheringi ezishushu eziphezulu neziphantsi ezineekheyiji zentsimbi ezicinezelweyo kwaye ezingenazo izitywini, umxube we-polydiol kunye ne-graphite usetyenziswa njenge-lubricant, kwaye zinokusebenza ngaphakathi koluhlu lobushushu oluphakathi kwe--40°C ukuya kwi-250°C. Nangona kunjalo, xa zisetyenziswa kwiindawo ezishushu eziphezulu ngaphezulu kwe-200°C, kufuneka kukhethwe ii-lubricant eziqinileyo.
Iibheringi zobushushu obuphezulu ezinezigqubuthelo zothuli kumacala omabini zinokuthintela ezinye izinto ezingcolisayo ukuba zingangeni. Ezi bearing zizaliswa kwangaphambili nge-lubricant ephindwe kabini kuneebheringi eziqhelekileyo, kodwa azifanelekanga ukusetyenziswa ezingajikeleziyo. Kwiibheringi ezisetyenziswa kubushushu obuphezulu, iibhloko zegrafiti ezihlukanisweyo zisetyenziswa njengezigcini zeekheyiji. Uluhlu lobushushu bokusebenza luqala kwi -150°C ukuya kwi +350°C. Ezi bhloko zegrafiti ezihlukanisweyo zahlula iibhola kwaye zisebenza njengekheyiji eqhelekileyo, ngelixa zisebenza njenge-lubricant. Izigqubuthelo zothuli kumacala omabini eebheringi zinokukhokela iibhloko zegrafiti ngaphakathi kwaye zithintele ukungena kwezinto ezingcolisayo eziqinileyo. Xa iibheringi zijikeleza, inani elincinci lomgubo wegrafiti kwiibhloko zegrafiti liyawa ukuze lithambise iindlela zomdyarho kunye neebhola zeebheringi. Enye inzuzo yolu yilo kukuba alunampembelelo imbi kwindalo esingqongileyo, njengoko kungekho gesi okanye umphunga oyingozi okhutshwayo nokuba kubushushu obuphezulu kakhulu.
Le bearing, ifanelekile kumaqondo obushushu aphezulu kunye nesantya esiphezulu sokujikeleza, yimveliso ephambili kuluhlu lweebearing ezikumgangatho ophezulu. Inekheyiji ecocekileyo yegraphite eyilwe ngokukodwa, esombulula imida emininzi edibana nayo kwiindlela zokusebenzisa kumaqondo obushushu aphezulu.
