1. Ma rollers ari mumutsara anosangana nemijaho, ane simba guru rekutakura radial, uye akakodzera kutakura zvinhu zvinorema uye zvinotyisa.

2. Iko friction coefficient idiki, inokodzera kukurumidza kukurumidza, uye iyo yekumisa kumhanya iri pedyo neyakadzama groove ball bearings.

3. Mienzaniso N uye NU inogona kufamba axially, inogona kuenderana nekushandurwa kwechinzvimbo chehukama che shaft uye imba nekuda kwekuwedzera kwekushisa kana kukanganisa kwekuisa, uye inogona kushandiswa sekusununguka kwekupedzisira kutsigirwa.Mhete yemukati kana yekunze inogona kuparadzaniswa kuti zvive nyore kuisa uye kubvisa.

4. Izvo zvinodiwa zvekugadzirisa shaft uye gomba rechigaro zvakanyanyisa.Iko kutsauswa kwehukama kwemukati nekunze kwemhete mhete mushure mekunge fanidzo yaiswa inofanira kunyatsodzorwa kudzivirira kukonzeresa kusangana kwekushushikana.

5.Double-row cylindrical roller bearings ine 1:12 taper mukati mebore.Iyo radial clearance inogona kugadziriswa uye iyo radial rigidity yakakwira, iyo inokodzera muchina chishandiso spindle.
