Wind Turbine Integrated Main Bearing Housing Casting with CNC Machining

Our integrated bearing housings are custom-manufactured according to customer drawings and specifications. They can be supplied for medium-speed, semi-direct drive, and direct-drive wind turbines in various MW classes. Dimensions, interfaces, and machining tolerances are fully tailored to the drivetrain requirements.

Yes. HNHJ offers integrated manufacturing from casting to CNC machining. Complete machining of bearing bores, flange faces, mounting interfaces, and critical dimensions is performed in-house, reducing dimensional deviations and avoiding risks associated with outsourced processing.

Critical dimensions are inspected using CMM, laser tracking systems, and other precision measuring equipment. UT, MT, and mechanical property tests are also available to ensure compliance with customer specifications and quality requirements.

Yes. Low-temperature ductile iron grades can be supplied to meet impact toughness requirements for onshore and offshore wind turbines operating in cold environments. Mechanical properties and impact test reports are available upon request.

An integrated bearing housing provides higher structural rigidity and better alignment accuracy, helping reduce assembly errors and improve load distribution. It is widely used in modern medium-speed and high-power wind turbine drivetrain systems.
