Pali mitundu yambiri yama bere.Pakati pawo, mayendedwe a mpira wakuya ndi amodzi mwa ma fani a mpira wa radial.Pogwiritsa ntchito, mayendedwe a mpira wakuya ali ndi mipira yakuya yothamanga kwambiri, yolondola kwambiri, phokoso lochepa komanso kugwedezeka, ndipo makamaka katundu wonyamula ma radial Bearings ali ndi makhalidwe atatu akuluakulu.Kutengera kugwiritsiridwa ntchito kwa ma bearings osiyanasiyana akuya a groove mpira, amakhalanso ndi mitundu yosiyanasiyana ya mayendedwe a mpira wakuya.

Malinga ndi kumvetsetsa kwapadera kwa mikhalidwe itatu yayikulu ya mayendedwe a mpira wakuya ndi mitundu ina:

Mbali yoyamba: Ili ndi mphete yakunja, mphete yamkati, gulu la mipira yachitsulo ndi gulu la makola.

Chigawo chachiwiri: Imanyamula katundu weniweni wa radial, komanso imatha kunyamula katundu wolumikizana.Ikayikidwa pamtundu wa radial yoyera, ngodya yake yolumikizana ndi ziro;ikakhala ndi sewero lalikulu la radial, imakhala ndi magwiridwe antchito ndipo imatha kupirira katundu wamkulu wa axial.Ma berelo a mpira wakuya amakhala ndi mikangano yaying'ono komanso kuthamanga kwambiri, kotero kuti ma axial loads akamathamanga kwambiri, amakhala apamwamba kuposa ma thrust bear.Komabe, chifukwa cha ntchito yake yochepa yodzigwirizanitsa, kukhazikika kwa kuyika kwazitsulo kuyenera kukhala kwakukulu, mwinamwake kungakhudze momwe ntchito yake ikuyendera, kuonjezera kupsinjika maganizo, ndikufupikitsa moyo wogwira ntchito.

3: Mapangidwe a mayendedwe ozama a mpira ndi osavuta, ndipo ndi osavuta kukwaniritsa zolondola kwambiri kuposa mitundu ina, kotero amatha kupangidwa m'magulu.Kuphatikiza pamitundu yodziwika bwino, ilinso ndi mitundu yosiyanasiyana yamapangidwe, monga mayendedwe a mpira wakuya groove okhala ndi chivundikiro cha fumbi, mayendedwe a mpira wakuya wokhala ndi mphete za mphira, mayendedwe ozama a mpira okhala ndi ma groove ndi zina zotero.
