Bearings na roller sune muhimman abubuwan da ake amfani da su a cikin injunan yadi, haɗakar motoci, akwatunan gear na masana'antu, da manyan injuna, suna taka muhimmiyar rawa wajen rage gogayya da kuma tabbatar da motsi mai santsi na juyawa. A tsarin gini, bearings na roller na yau da kullun ya ƙunshi mandrel 1 da bearings masu inganci waɗanda aka ɗora a ƙarshen biyu, waɗanda aka ƙera su don jure wa yanayin aiki mai tsauri a wurare daban-daban na masana'antu. A matsayin manyan abubuwan da ke cikin tsarin watsawa na inji, amincin su yana tasiri kai tsaye ga inganci, tsawon rai, da amincin aiki na dukkan kayan aiki.

An rarraba jerin bearings na naɗi bisa tsari bisa ga muhimman sharuɗɗa guda biyu: siffa da ƙira. Rarraba siffofi sun haɗa da bearings na naɗin silinda, bearings na naɗin da aka yi da tapered, bearings na naɗin mai siffar ƙwallo, da bearings na naɗin allura, kowannensu ya dace da takamaiman buƙatun kaya da sarari. Bambancin ƙira ya shafi tsarin layi ɗaya ko jere biyu, ƙira masu lanƙwasa ko marasa lanƙwasa, tsarin da aka rufe ko buɗe, duk an inganta su don magance haɗuwa daban-daban na nauyin radial mai nauyi, nauyin axial, saurin juyawa mai yawa, da rashin daidaiton shaft.

Fahimtar manyan nau'ikan bearings na nadi yana da mahimmanci wajen yanke shawara mai kyau game da zaɓe:

Bearings na birgima masu silinda sun fi kyau wajen sarrafa manyan kaya masu nauyi da kuma saurin juyawa, kuma suna iya ɗaukar ɗan canjin axial sai dai idan an haɗa zoben biyu da flange - wanda hakan ya sa suka dace da na'urorin birgima na injin yadi da kuma shafts na injin lantarki. An ƙera bearings masu tauri don tallafawa haɗakar kayan axial masu girma da kuma waɗanda ke da shugabanci ɗaya, kuma ana yawan amfani da su a nau'i-nau'i a cikin cibiyoyin ƙafafun mota da akwatunan gearbox na masana'antu don daidaita ƙarfin hanya biyu.

Bearings na juyawa masu siffar siffa sun shahara saboda iyawarsu ta ɗaukar nauyin radial mai nauyi, nauyin axial mai kusurwa biyu, da kuma gyara kuskuren shaft ta atomatik wanda kurakuran shigarwa ko karkacewar aiki suka haifar, wanda hakan ya sa suka dace da kayan aiki masu nauyi kamar tsarin jigilar kaya da injinan haƙar ma'adinai. Bearings na juyawa masu allura, tare da ƙaramin tsari da ƙarfin ɗaukar kaya idan aka kwatanta da girmansu, sune manyan zaɓi don aikace-aikace tare da ƙarancin sararin shigarwa, kamar famfunan hydraulic da watsawa na mota.

An ƙera bearings na thrust, gami da bearings na thrust, musamman don jure wa manyan lodi na axial, waɗanda aka saba amfani da su a cikin sandunan kayan aikin injin da hanyoyin lif.

Tsarin zaɓar madaidaicin abin nadi ya ƙunshi cikakken kimantawa na mahimman sigogin aiki:
da farko, gano nau'in da girman nauyin (radial, axial, ko a hade);
na biyu, ƙayyade saurin juyawa da matakin daidaito da ake buƙata (yana da mahimmanci ga aikace-aikacen da suka dace kamar injunan CNC);
na uku, yi la'akari da kewayon zafin aiki (don zaɓar bearings tare da kayan da suka dace masu jure zafi);
kuma a ƙarshe, a tantance iyakokin sarari don tabbatar da cewa bearing ɗin ya dace da akwatin ƙirar kayan aikin.
