Chifaniziro cha fan ndi mtundu wa bearing, womwe umatanthauza mtundu wa bearing womwe fan ya radiator yozizira mpweya imagwiritsa ntchito.
Mu uinjiniya wamakina, pali mitundu yambiri ya ma bearing, koma pali mitundu yochepa yokha yomwe imagwiritsidwa ntchito popanga ma radiator: ma bearing a sleeve pogwiritsa ntchito sliding friction, ma bearing a mpira pogwiritsa ntchito rolling friction, ndi kusakaniza mitundu iwiri ya ma bearing. M'zaka zaposachedwa, opanga ma radiator akuluakulu ayambitsa ukadaulo watsopano wa ma bearing, monga ma magnetic bearing, ma wave wave bearing, ma magnetic core bearing, ndi ma hinge bearing. . Ma radiator wamba oziziritsidwa ndi mpweya makamaka amagwiritsa ntchito ma bearing odzazidwa ndi mafuta ndi ma ball bearing.
Ma bearing odzazidwa ndi mafuta ndi ma bearing a manja omwe amagwiritsa ntchito kutsetsereka. Mafuta opaka mafuta amagwiritsidwa ntchito ngati mafuta odzola komanso chochepetsera kukoka. Poyamba, phokoso logwira ntchito limakhala lotsika ndipo mtengo wopanga nawonso ndi wotsika. Komabe, mtundu uwu wa bearing umatha kwambiri, ndipo moyo wake wogwirira ntchito uli wocheperako kuposa wa ma bearing a mpira. Komanso, ngati mtundu uwu wa bearing ugwiritsidwa ntchito kwa nthawi yayitali, chifukwa cha chifukwa cha chisindikizo cha mafuta (sikutheka kugwiritsa ntchito chisindikizo chamafuta chapamwamba pazinthu zoyatsira ma radiator apakompyuta, nthawi zambiri ndi chisindikizo chamafuta wamba), mafuta opaka mafuta amasinthasintha pang'onopang'ono, ndipo fumbi lidzalowanso mu bearing, zomwe zimapangitsa fan. Liwiro limakhala locheperako, phokoso limawonjezeka ndi mavuto ena. Pazochitika zazikulu, kusinthasintha kwa fan komwe kumachitika chifukwa cha kuvala kwa bearing kungayambitse kugwedezeka kwakukulu. Ngati izi zichitika, tsegulani chisindikizo chamafuta kuti mudzaze mafuta, kapena muyenera kuchotsa ndikugula fan yatsopano.
Chimbalangondo cha mpira chimasintha kachitidwe ka kukangana kwa bearing, ndikugwiritsa ntchito kukangana kozungulira, komwe kumachepetsa bwino kukangana pakati pa malo okangana, kumawongolera bwino moyo wa ntchito ya bearing ya fan, motero kumatalikitsa moyo wa ntchito ya radiator. Vuto lake ndilakuti njirayi ndi yovuta kwambiri, zomwe zimapangitsa kuti mtengo wake ukwere komanso phokoso lokwera.
