Ukuqina kwe-bearing kungamandla adingekayo ukwenza i-bearing deformation.I-deformation elastic of rolling bearings incane kakhulu futhi inganakwa emishinini eminingi.Kodwa-ke, kweminye imishini, njengama-spindle amathuluzi omshini, ukuqina kuyisici esibalulekile.Ama-roller bearings angama-cylindrical kanye nama-tapered ngokuvamile asetshenziswa.Ngenxa yokuthi lezi zinhlobo ezimbili zama-bearings zingaphansi komthwalo, izakhi ezigoqayo kanye nemigwaqo yomjaho kuxhumene nomugqa, futhi ukuguqulwa kwe-elastic kuncane futhi ukuqina kuhle.Zonke izinhlobo zama-bearings zingabuye ziqiniswe ngaphambili ukuze kwandiswe ukuqina kokusekelwa.Isibonelo, ama-angular ball bearings kanye nama-roller bearings tapered, ukuze kuvinjwe ukudlidliza kwe-shaft futhi ukwandise ukuqina kokusekelwa, i-axial force ethile ivame ukusetshenziswa ngesikhathi sokufakwa ukuze ucindezele ngokumelene nomunye nomunye.Yiqiniso, inani lokuqinisa ngaphambilini akufanele libe likhulu kakhulu.Uma kukhulu kakhulu, ukungqubuzana okuthwala kuzokwanda futhi ukunyuka kwezinga lokushisa kuzokwanda, okuzothinta impilo yesevisi yokuthwala.
