Bomoi ya roulement esimbami na makambo mingi, na kati na yango lolenge, bonene, matériel, lolenge ya kopakola, mpe esika ya mosala. High-Ba roulements ya qualité mingi mingi ezalaka na bomoi molai na ba conditions normales ya fonctionnement, kasi ba valeurs spécifiques ezali difficile ya ko standardiser. Ba roulements rouleaux ebongi mpo na ba applications ya likolo{3}}Load (capacité ya charge ya likolo), alors que ba roulements à billes ebongi pona ba applications ya likolo{4}}vitesse, basse{5}}Load. Mingimingi, roulements ya minene ezalaka na bomoi molai. Traitement ya chaleur ya haute-Acier ya alliage ya qualité ematisaka duresse na yango (HRC 58-62) mpe elataka résistance, na yango ebakisaka vie. Méthode ya lubrification ezali crucial mpo na vie. Lubrification ya malamu ekitisaka friction (coefficient ya friction .<0.0015) and lowers temperature rise (<80°C). Harsh environments (such as high temperatures >120°C and high humidity >80% RH) ekoki kosala ete bomoi ezala mokuse mpenza.
Generator bearings require high load capacity (dynamic load >50kn) mpe résistance ya kolata, mpe bokangami (IP65 rating) mpo na kobatela na mputulu mpe mai. Bobateli ya mbala na mbala (kotala lubrification na ngonga nyonso ya 500) mpe kopona ya likolo-Ba roulements ya qualité (lokola biloko oyo ezwami na certificat ya ISO 9001) ekoki koyeisa bomoi ya bomoi.
