Kutentha ndi chinthu chosapeŵeka panthawi yogwira ntchito ya bearing. Muzochitika zachizolowezi, kutentha ndi kutayika kwa kutentha kwa bearing kudzafika pamlingo wofanana, ndiko kuti, kutentha komwe kumatulutsidwa ndi kutentha komwe kumachotsedwa kumakhala kofanana, kotero kuti makina operekera zakudya azikhala ndi kutentha kokhazikika.
Kutengera kukhazikika kwa zinthu zonyamulira komanso mafuta omwe amagwiritsidwa ntchito, kutentha kwa zinthu zonyamulira kumayendetsedwa pa 95°C ngati malire apamwamba. Ngakhale kuonetsetsa kuti makina onyamulira akukhazikika, sizikhudza kwambiri kukwera kwa kutentha kwa makinawo.mota yopanda corelesszozungulira.
Zomwe zimayambitsa kutentha m'makina oyendetsera galimoto ndi mafuta ndi njira zoyenera zochotsera kutentha. Komabe, panthawi yopanga ndi kugwiritsa ntchito injini, makina oyendetsera galimoto sangagwire ntchito bwino chifukwa cha zinthu zina zosayenera.
Pamene malo ogwirira ntchito a bearing ndi ochepa kwambiri ndipo kuyenererana pakati pa bearing ndi shaft kapena chipinda choperekera zinthu kuli kotayirira, kumayambitsa kuzungulira koyenda; pamene ubale wa axial fit wa bearing wasokonekera kwambiri chifukwa cha mphamvu ya axial; kuyenererana kosafunikira pakati pa bearing ndi zigawo zina zokhudzana nazo kumayambitsa mafuta Zinthu zosafunikira monga mafuta omwe amatayidwa kunja kwa bearing cavity zimapangitsa kuti bearing itenthe panthawi yogwira ntchito ya injini. Mafutawo adzawonongeka ndikulephera chifukwa cha kutentha kwambiri, zomwe zimapangitsa kuti makina operekera zinthu a injiniyo akumane ndi tsoka lalikulu pakapita nthawi yochepa. Chifukwa chake, kaya ndi njira yopangira kapena kupanga injiniyo, komanso kukonza ndi kusamalira injiniyo pambuyo pake, kukula kwa ubale wogwirizana pakati pa zigawozo kuyenera kulamulidwa.
Mphamvu ya shaft ndi chiwopsezo chosapeweka cha mtundu wa injini zazikulu, makamaka ma mota amphamvu kwambiri ndi ma mota osinthasintha. Mphamvu ya shaft ndi vuto lalikulu kwambiri pa makina oyendera magetsi amota yopanda corelessNgati njira zofunikira sizitengedwa, makina operekera magetsi amatha kuwonongeka pakangopita masekondi ochepa chifukwa cha mphamvu ya shaft current. Kusweka kumachitika mkati mwa maola khumi kapena maola ochepa. Vuto lamtunduwu limadziwonekera ngati phokoso la mabearing ndi kutentha kumayambiriro kwa kulephera, kutsatiridwa ndi kulephera kwa mafuta chifukwa cha kutentha, ndipo mkati mwa nthawi yochepa, vuto la kugwira shaft chifukwa cha kuchotsedwa kwa mabearing limachitika. Pachifukwa ichi, ma mota amphamvu kwambiri, ma mota osinthasintha, ndi ma mota amphamvu otsika mphamvu adzatenga njira zofunikira pagawo lopanga, gawo lopanga, kapena gawo logwiritsa ntchito. Pali ziwiri zofanana. Choyamba ndikudula dera (monga kugwiritsa ntchito ma bearing otetezedwa, ma Insulating end caps, ndi zina zotero), china ndi njira yodutsa magetsi, ndiko kuti, kugwiritsa ntchito burashi ya kaboni yokhazikika kuti itsogolere mphamvu kuti ipewe kuukira kwa makina operekera magetsi.
