Forged Products for Wind Power

FRISA is a leading forging supplier for the wind power generation industry. Our product portfolio includes seamless rolled rings and open die forgings that offer increased value to our customers through proven performance, reliability, and availability.

The main applications of our products include:

Shafts A wind turbine’s main shaft must withstand axial and radial loads and operate under harsh, continuously changing conditions. We can provide forging solutions for main shaft bearing arrangements.

Bearings When it comes to wind turbine bearings, manufacturers need a supplier with the experience and capability to support critical pitch, yaw and main hub bearings applications. We carry various steel grades like 42CrMo4 and 52100 among many others.

Flanges The tower supports the weight of the nacelle and rotor hub, and must be strong enough to withstand the movement caused by the force of the wind upon the blades. Our flanges connect tower sections, offering strength and flexibility to endure tough conditions. Typical steel grades include A694 F42 and S355NL, and most of our rings are contoured.

Gears Our focus is to supply rings that comply with the most stringent requirements. We normally carry steel grades including: 30CrNiMo8, 34CrNiMo6, 18CrNiMo7-6, 42CrMo4, etc. Some of the rings that we supply are for the following gearbox components: Ring Gears, Bull Gear, Planetary Gears, Output Gear, and Quill Shaft.

Couplings The coupling assures the transmission of the torque between the gearbox and generator. We normally carry steel grades like: 42CrMo4, and F22.


The most common materials grades FRISA provides for the wind power industry include EN355B, 42CrMo4 alloy steel, ASTM A350 Grade LF6, and 1552.


FRISA has the equipment and technical knowledge to supply turnkey solutions. For new Wind Farms, planning for high volume projects is of the utmost importance. Our technical team understands this need and provides a just in time production system that allows us to eliminate inventory, provide cost effectiveness, all while maintaining the flexibility needed to supply low quantity orders for replacement parts.

Delivery and Logistics

As the outside diameter of the flanges that we can supply can go as 315”, the transportation for a finished machine flange can be challenging. We have the expertise and supply chain delivery to ship oversized rings anywhere- land or by sea.
