Key features

Thick-section hubs are poured so flange faces and bolt holes stay sound after machining.

Low-temperature ductile iron is available when the hub must keep toughness in cold service.

Hubs can ship as-cast or CNC machined to the blade and main shaft interfaces.

UT, MT, and mill certificates can follow the inspection plan on your order.

This hub is for utility-scale wind turbines, not residential or small-wind machines.

Product Q&A

Q:Is this hub for residential or small wind turbines?

No. This is a large industrial hub for utility-scale onshore and offshore wind turbines, made to OEM drawings.

Q:Can you supply the hub as-cast, or fully machined?

Both. We can deliver a rough casting or a machined hub, including flange faces, bores, and bolt holes, to your drawing.

Q:What material do you pour for the hub?

Typically low-temperature ductile iron such as EN-GJS-400-18-LT, or the grade named on your specification.

Q:What inspection documents come with the hub?

Material test results, heat-treatment records if required, a dimensional report, and NDT reports such as UT and MT, as specified in the order.

Q:What do you need to quote a hub?

A drawing or 3D model, material grade, delivery condition (as-cast or machined), quantity, and any NDT or coating requirements.
