Mabearing ndi zinthu zomwe zimakonza ndikuchepetsa kuchuluka kwa kugwedezeka kwa katundu panthawi yotumiza makina. Zinganenedwenso kuti zinthu zina zikapanga kayendedwe kake pa shaft, imagwiritsidwa ntchito kuchepetsa kuchuluka kwa kugwedezeka kwa katundu panthawi yotumiza mphamvu ndikusunga malo okhazikika a shaft center. Mabearing ndi chinthu chofunikira kwambiri pazida zamakono zamakanika. Ntchito yake yayikulu ndikuthandiza thupi lozungulira lakanika kuti lichepetse kuchuluka kwa kugwedezeka kwa katundu wamakina panthawi yotumiza makina. Malinga ndi mawonekedwe osiyanasiyana a kugwedezeka kwa zinthu zosuntha, mabearing amatha kugawidwa m'mitundu iwiri: mabearing ozungulira ndi mabearing otsetsereka. 1, Pali ngodya yolumikizana pakati pa kukhudzana kwa angularchogwirira mpiramphete ndi mpira. Ma ngodya olumikizirana wamba ndi 15 °, 30 °, ndi 40 °. Ngodya yolumikizirana yayikulu, mphamvu ya axial load imakula. Ngodya yolumikizirana yaying'ono, imakhala yothandiza kwambiri kuzungulira mwachangu. Ma bearing a mzere umodzi amatha kupirira katundu wa axial wozungulira komanso wozungulira. Mwa kapangidwe kake, ma bearing awiri a mzere umodzi a angular contact ball omwe ali ndi mzere umodzi wokhala ndi mzere umodzi wokhala ndi mzere umodzi wokhala ndi mzere umodzi wokhala ndi mphete zamkati ndi zakunja, zomwe zimatha kupirira katundu wa axial wozungulira komanso wozungulira. Ntchito zazikulu za ma bearing a angular contact ball: mzere umodzi: spindle ya chida chamakina, mota yothamanga kwambiri, turbine ya gasi, separator ya centrifugal, gudumu laling'ono lakutsogolo la galimoto, shaft yosiyanitsa. Mzere wawiri: pampu yamafuta, Roots blower, compressor yampweya, ma transmission osiyanasiyana, pampu yopangira mafuta, makina osindikizira. 2、 Bearing ya mpira wodziyimira yokha ili ndi mizere iwiri ya mipira yachitsulo, ndipo mtundu wakunja ndi wa mtundu wa mpira wamkati. Chifukwa chake, imatha kusintha yokha kusalingana kwa shaft chifukwa cha kupindika kapena kusakhazikika kwa shaft kapena chipolopolo. Bearing yoboola pang'ono imatha kuyikidwa mosavuta pa shaft pogwiritsa ntchito zomangira, makamaka zonyamula katundu wa radial. Kugwiritsa ntchito kwakukulu kwa ma bearing a mpira odzipangira okha: makina opangira matabwa, ma shaft otumizira makina a nsalu, ma bearing odzipangira okha okhala ndi mipando yowongoka. 3, Bearing yodzipangira yokha Mtundu uwu wa bearing uli ndi ma rollers ozungulira pakati pa mphete yakunja ya msewu wozungulira ndi mphete yamkati ya msewu wozungulira wawiri. Malinga ndi kapangidwe ka mkati kosiyanasiyana, ukhoza kugawidwa m'mitundu inayi: R, RH, RHA, ndi SR. Chifukwa cha kusinthasintha pakati pa arc center ya msewu wakunja ndi pakati pa bearing, imakhala ndi magwiridwe antchito odzipangira okha. Chifukwa chake, imatha kusintha yokha misalignment ya axis yomwe imachitika chifukwa cha kupotoka kapena kusakhazikika kwa shaft kapena chipolopolo, ndipo imatha kupirira misalignment ya radial.
