Mabheyaringi ndiwo mativi akakosha mumunda wekugadzira michina yeindasitiri. Kana kuoma kwebheyaringi kwakakwira, simba rebheyaringi rinoramba kupera, uye simba rechinhu chacho rakakwirira, kuitira kuti beyari ikwanise kumira mitoro yakawanda uye ishande kwenguva yakareba. Saka, kuoma kwayo kwemukati kunokosha zvikuru pahupenyu hwayo hwekushanda uye kunaka kwayo.
Pakuyedzwa kwekuoma kwesimbi nesimbi isina ferrous metal bearing parts mushure mekudzima nekudzikamisa uye kupedza bearing parts nesimbi isina ferrous bearing parts, nzira huru dzekuyedza dzinosanganisira Rockwell hardness test method, Vickers hardness test method, tensile strength test method uye Leeb hardness test method, nezvimwewo. Pakati padzo, nzira mbiri dzekutanga dzakarongeka uye dzakajairika mukuyedzwa, uye Brinell method zvakare inzira iri nyore uye yakajairika, nekuti test indentation yayo yakakura uye haishandiswi zvakanyanya.
Nzira yekuyedza kuomarara kweRockwell inoshandiswa zvakanyanya muindasitiri yemabheyaringi, uye zvinhu zvayo zvikuru zviri nyore uye zvinokurumidza.
Chinoongorora kuomarara cheRockwell chiri nyore kushandisa. Chinongoda chete kurodha simba rekutanga rekuyedza uye chinoongorora kuomarara chinowana otomatiki kukosha kwekuomarara.
Nzira yekuedza kuomarara yeVickers yakanangana nekuyedza kuomarara kweshaft yebearing uye roller yakatenderera yebearing. Inofanira kucheka nekuita sampuro yekuyedza kuti iwane kukosha kwesimba reVickers.
