The Wind Turbine Main Shaft Bearing Housing minangka komponen struktural dhasar ing turbin angin sumbu horisontal, tanggung jawab kanggo ndhukung poros rotor lan ngirimake beban aerodinamis menyang pigura nacelle. Dioperasikake kanthi loading siklik sing terus-terusan, variasi suhu sing ekstrem, lan syarat umur layanan 20+ taun, komponen iki mbutuhake kekuatan lemes sing luar biasa, stabilitas dimensi, lan soundness metalurgi.
Ningbo Ruican mrodhuksi omah iki liwat casting investasi tliti saka QT700-2 wesi ductile, ngiring dening 5-sumbu mesin CNC lumahing prewangan kursi kritis, pola bolongan bolt, lan soyo tambah antarmuka. Manufaktur terpadu kita njamin traceability lengkap saka bahan mentah nganti komponen rampung.
