Kukhala ndi moyo kumakhudzidwa ndi zinthu zambiri, kuphatikiza mtundu, kukula, zinthu, njira yothira mafuta, ndi malo ogwirira ntchito. -ma bere apamwamba kwambiri amakhala ndi moyo wautali pansi pazikhalidwe zanthawi zonse, koma zofunikira zenizeni zimakhala zovuta kuziyika. Marola ndi oyenera kugwiritsa ntchito-zolemetsa zambiri (kuchuluka kwambiri), pomwe ma berelo ndi oyenera kugwiritsa ntchito-liwiro, lotsika-ndi kuloza kwambiri. Ma bere akuluakulu amakhala ndi moyo wautali. Kutenthetsa kutentha kwapamwamba-kumapangitsa kulimba kwake (HRC 58-62) ndi kusagwira ntchito, motero kumatalikitsa moyo. Njira yothira mafuta ndiyofunikira pa moyo wonse. Mafuta abwino amachepetsa kukangana (friction coefficient<0.0015) and lowers temperature rise (<80°C). Harsh environments (such as high temperatures >120°C and high humidity >80% RH) imatha kufupikitsa moyo wautali.
Generator bearings require high load capacity (dynamic load >50kN) ndi kuvala kukana, ndi kusindikiza (IP65 mlingo) kuteteza ku fumbi ndi madzi. Kusamalira nthawi zonse (kuyang'ana mafuta pa maola 500 aliwonse) ndi kusankha-ma bearings apamwamba kwambiri (monga zinthu zotsimikiziridwa ndi ISO 9001) kungatalikitse moyo.
