ʻO ka Marine Propeller Hub ka mea i kūkulu ʻia i waena o kahi ʻōnaehana hoʻokele kai, e hoʻopili ana i nā lau propeller i ke kumu propulsion a me ka hoʻouna ʻana i ka ʻenekini torque e hoʻoulu ai i ka pana. Ke hana nei i loko o ka wai kai koʻikoʻi, pono ka hub e pale i ka corrosion, cavitation erosion, a me galvanic attack me ka mālama ʻana i ka ikaika mechanical kiʻekiʻe a me ke kiko kikoʻī no ka kau ʻana o ka lau.
Hana ʻo Ningbo Ruican i kēia hub me ka hoʻohana ʻana i ka hoʻoheheʻe kālā pololei ʻana o C95800 nickel-aluminum bronze (NAB), kahi mea kaulana no kona kūpaʻa kūʻokoʻa wai kai, ikaika hua kiʻekiʻe, a me nā waiwai anti-biofouling. ʻO kā mākou CNC machining e hōʻoia i ka pololei o nā moʻo aʻa o ka lau, ka taper bore, a me nā ʻāpana kī i ka pololei o nā kūlana kai.
