Bearings abubuwa ne da ke gyarawa da rage yawan gogayya a yayin watsawa ta injina. Haka kuma, ana iya cewa lokacin da wasu sassa ke haifar da motsi a kan shaft, ana amfani da shi don rage yawan gogayya a lokacin watsawa ta wutar lantarki da kuma kula da matsayi mai tsayayyen tsakiyar shaft. Bearings muhimmin sashi ne a cikin kayan aikin injiniya na zamani. Babban aikinsa shine tallafawa jikin juyawa na injiniya don rage yawan gogayya a cikin kayan aikin yayin aikin watsawa. Dangane da halaye daban-daban na gogayya na abubuwan motsi, ana iya raba bearings zuwa nau'i biyu: bearings masu birgima da bearings masu zamiya. 1, Akwai kusurwar hulɗa tsakanin hulɗar kusurwaƙwallo mai ɗauke da ƙugiyaZobe da ƙwallon. Kusurwoyin hulɗa na yau da kullun sune 15 °, 30 °, da 40 °. Mafi girman kusurwar hulɗa, mafi girman ƙarfin ɗaukar nauyin axial. Ƙaramin kusurwar hulɗa, mafi dacewa da juyawa mai sauri. Bearings na layi ɗaya na iya jure nauyin axial na radial da unidirectional. A tsarin gini, bearings na ƙwallon hulɗa na layi ɗaya guda biyu tare da haɗin baya suna raba zoben ciki da na waje, waɗanda zasu iya jure nauyin axial na radial da bidirectional. Babban amfani da bearings na ƙwallon hulɗa na kusurwa: layi ɗaya: spindle na kayan aikin injin, injin mai yawan mita, injin turbine na gas, mai raba centrifugal, ƙaramin ƙafafun gaba na mota, shaft ɗin pinion daban-daban. Ginshiƙi biyu: famfon mai, injin hura tushen, na'urar compressor na iska, watsawa daban-daban, famfon allurar mai, injinan bugawa. 2, Bearing ɗin ƙwallon daidaitawa mai kai tsaye yana da layuka biyu na ƙwallan ƙarfe, kuma tseren waje na nau'in saman ƙwallon ciki ne. Saboda haka, yana iya daidaita daidaiton shaft ta atomatik sakamakon lanƙwasawa ko rashin daidaituwa na shaft ko harsashi. Ana iya shigar da beyar rami mai kauri cikin sauƙi a kan shaft ta amfani da maƙallan ɗaurewa, waɗanda galibi ke ɗauke da nauyin radial. Babban amfani da beyar ƙwallon da ke daidaita kanta: injinan aikin katako, sandunan watsa injinan yadi, beyaran daidaitawa kai tsaye na kujera. 3, Beyar naɗi mai daidaita kai Wannan nau'in beyar an sanye shi da na'urori masu zagaye tsakanin zoben waje na hanyar tsere mai zagaye da zoben ciki na hanyar tsere mai zagaye biyu. Dangane da tsarin ciki daban-daban, ana iya raba shi zuwa nau'i huɗu: R, RH, RHA, da SR. Saboda daidaito tsakanin tsakiyar baka na hanyar tsere ta waje da tsakiyar beyar, yana da aikin daidaitawa kai tsaye. Saboda haka, yana iya daidaita daidaiton axis ta atomatik wanda karkacewa ko rashin daidaituwa na shaft ko harsashi ya haifar, kuma yana iya jure rashin daidaiton radial.
