Gawo lachitatu moterema bearings amatenga gawo lofunikira pakuyendetsa bwino kwa makina, ndipo kumvetsetsa momwe amagwirira ntchito ndikofunikira kuti akonze bwino komanso kuti azigwira bwino ntchito. Chochitika chodziwika bwino pamayendedwe amoto ndi "kuzungulira," komwe kumachitika chifukwa cha kukwanirana pakati pa chipinda chonyamulira, shaft, ndi chotengera. Kuyenerera kumeneku nthawi zambiri kumakhala kovomerezeka komwe kumalola kuti pakhale kuyenda pakati pa zigawozo.
Pamene injini ikugwira ntchito, mphamvu za torsional zimawononga chikhalidwe chokhazikika cha msonkhano wonyamula. Kuwonongeka kumeneku kungayambitse kutsetsereka pakati pa zigawo zikuluzikulu, makamaka pakati pa mphete yamkati ndi shaft, chodabwitsa chomwe chimatchedwa "kutsetsereka kwa mphete yamkati." Mofananamo, kutsetsereka kumachitika pakati pa mphete yakunja yonyamula ndi chipinda chonyamula, chomwe chimatchedwa "ring ring running". Mitundu yonse iwiri yotsetsereka imatha kukhudza kwambiri magwiridwe antchito komanso moyo.
Chifukwa chachikulugawo atatu induction motormayendedwe omwe amazungulira mozungulira ndi kusalinganika komwe kumachitika chifukwa cha kutsetsereka uku. Pamene mphete yamkati imayenda molingana ndi tsinde, imayambitsa kuvala kosagwirizana, zomwe zimapangitsa kuti chigawocho chiwonongeke. Kusalongosoka kumeneku kumakulitsa kusuntha kotsetsereka, kumapanga njira yobwereza yomwe imalepheretsanso kukhazikika kwake. Zotsatira zake, ma bearings sangayende bwino, zomwe zimapangitsa kugwedezeka komanso kulephera.
Kuphatikiza apo, zinthu monga kudzoza, kuchuluka kwa katundu ndi kutentha kumatha kukhudza kuchuluka kwa kutsetsereka komanso magwiridwe antchito onse. Kukonzekera koyenera, kuphatikizapo kuyang'anitsitsa nthawi zonse ndi mafuta odzola panthawi yake, kungathandize kuthetsa mavutowa ndikuonetsetsa kuti zitsulo zimagwira ntchito mkati mwa mapangidwe awo.
Kuti tichite zimenezi, phokoso chodabwitsa mu3 gawo asynchronous motamayendedwe amayambika makamaka chifukwa cholowera pakati pa chipinda chonyamulira, shaft ndi chipinda chonyamulira, komanso kutsetsereka komwe kumachitika chifukwa cha torque. Kumvetsetsa zosinthika izi ndikofunikira kuti mukhalebe ndi magwiridwe antchito abwino komanso kukulitsa moyo wobereka.
