Iyo Marine Propeller Hub ndiyo yepakati dhizaini chikamu chemugungwa propulsion system, inobatanidza mablades kune propulsion shaft uye kutumira injini torque kuti ibudise simba. Inoshanda munzvimbo dzakaoma dzemvura yegungwa, iyo hubhu inofanirwa kuramba corrosion, cavitation erosion, uye galvanic kurwisa ichichengetedza yakakwirira mechanicha simba uye dimensional chaiyo yekuisa blade.
Ningbo Ruican inogadzira hubhu iyi vachishandisa chaiyo mari yekukandira yeC95800 nickel-aluminum bronze (NAB), zvinhu zvinozivikanwa nekusaita corrosion yemvura yegungwa, simba regoho rakakura, uye anti-biofouling zvivakwa. Yedu CNC machining inovimbisa chaiyo blade midzi inotsvedza, taper bore, uye keyway zviyero kune chaiwo miitiro yegungwa.
