Ma bearings ndi zigawo zomwe zimakonza ndikuchepetsa kugundana kwa katundu panthawi yotumizira makina. Zingathenso kunenedwa kuti pamene zigawo zina zimapanga zoyenda pang'onopang'ono pa shaft, zimagwiritsidwa ntchito kuchepetsa kugunda kwapakati panthawi yotumiza mphamvu ndikusunga malo okhazikika a shaft center. Bearings ndi chinthu chofunikira kwambiri pazida zamakina zamakono. Ntchito yake yayikulu ndikuthandizira thupi lozungulira pamakina kuti muchepetse kugundana kwamakina kwa zida panthawi yotumizira. Malinga ndi mawonekedwe amitundu yosiyanasiyana yazigawo zosuntha, ma fani amatha kugawidwa m'mitundu iwiri: mayendedwe oyenda komanso otsetsereka. 1. Pali njira yolumikizirana pakati pa kukhudzana kwa angularkusewera mpiramphete ndi mpira. Mulingo wolumikizana ndi 15 °, 30 °, ndi 40 °. Kukula kolumikizana ndi ngodya, kumapangitsanso kuchuluka kwa axial katundu. Kang'ono kakang'ono kolumikizana, kamakhala kothandiza kwambiri kuzungulira kothamanga kwambiri. Mizere ya mzere umodzi imatha kupirira ma radial ndi unidirectional axial katundu. Mwachindunji, mizere iwiri yolumikizana ndi mizere yolumikizirana yolumikizana kumbuyo imagawana mphete zamkati ndi zakunja, zomwe zimatha kupirira ma radial ndi bidirectional axial load. Kugwiritsiridwa ntchito kwakukulu kwa mayendedwe ang'onoang'ono a mpira: mzere umodzi: makina opota, makina othamanga kwambiri, turbine ya gasi, cholekanitsa chapakati, gudumu lakutsogolo lagalimoto laling'ono, pinion shaft yosiyana. Mzere wapawiri: pampu yamafuta, chowotcha Mizu, kompresa ya mpweya, ma transmission osiyanasiyana, pampu ya jakisoni wamafuta, makina osindikizira. 2, The kudzikonda aligning mpira kubala ali ndi mizere iwiri ya mipira zitsulo, ndipo mtundu wakunja ndi wa mkati mpira pamwamba mtundu. Chifukwa chake, imatha kusinthiratu kusakhazikika kwa shaft chifukwa cha kupindika kapena kusakhazikika kwa shaft kapena chipolopolo. Bowo lokhala ndi tapered limatha kukhazikitsidwa mosavuta pa shaft pogwiritsa ntchito zomangira, makamaka zonyamula katundu wa radial. The ntchito yaikulu kudzikonda aligning mpira mayendedwe: matabwa makina, nsalu makina kufala shafts, ofukula mpando kudzikonda fani. 3, Self aligning wodzigudubuza kubala Mtundu uwu wa kubala ali okonzeka ndi odzigudubuza ozungulira pakati pa mphete yakunja ya ozungulira raceway ndi mphete yamkati ya mpikisano wapawiri. Malinga ndi mapangidwe amkati osiyanasiyana, amatha kugawidwa m'mitundu inayi: R, RH, RHA, ndi SR. Chifukwa cha kusasinthika pakati pa arc center of the arc raceway ndi pakati pa bearing, imakhala ndi magwiridwe antchito. Chifukwa chake, imatha kusintha ma axis molakwika chifukwa cha kupotokola kapena kusakhazikika kwa shaft kapena chipolopolo, ndipo imatha kupirira kulakwitsa kwa ma radial.
