Tlhaloso ea Sehlahisoa

 Wind Turbine Main Shaft Bearing Housing ke karolo ea motheo ea li-turbine tsa moea tse tšekaletseng, tse ikarabellang bakeng sa ho tšehetsa shaft ea rotor le ho fetisetsa meroalo ea aerodynamic foreiming ea nacelle. E sebetsa tlas'a phallo e sa khaotseng ea libaesekele, phapang e feteletseng ea mocheso, le litlhoko tsa bophelo ba tšebeletso ea lilemo tse 20+, karolo ena e hloka matla a ikhethang a mokhathala, botsitso ba sebopeho, le molumo oa metallurgical. 
 Ningbo Ruican e hlahisa ntlo ena ka ho etsa matsete a nepahetseng a QT700-2 ductile iron, e lateloang ke 5-axis CNC machining ea libaka tse mahlonoko tsa litulo, lipaterone tsa lesoba la bolt, le li-interfaces tse ntseng li phahama. Moetso oa rona o kopaneng o netefatsa ho ts'oara ka botlalo ho tloha ho thepa e tala ho isa karolong e felileng.
