Parts for tower and nacelle

As the machine centre, the nacelle is often considered the technical heart of a wind turbine. Carried by the tower, it contains many components from generator to gear that an operator must be able to rely on. Constructors therefore need reliable parts and materials for construction. We support you in this with our plastics. They convince, among others, with low weight at high strength, high corrosion resilience or good sliding properties. Thus, they offer benefits as compared to traditional materials, and help you construct reliable towers and nacelles.

Your advantages

  • High efficiency
  • High operating safety
  • Low-maintenance
  • Avoiding a slip-stick effect

Typical areas of application

  • Onshore wind turbines
  • Offshore wind turbines
  • Small wind turbines

Product examples

Sliding sheets in the Azimuth system

In the Azimuth system, sliding sheets made of SUSTARIN® C GLD 350 (POM) permit quick and precise alignment of the nacelle in the wind direction. Thanks to the self-lubricating properties, the nacelle moves quickly, evenly and with little energy expenditure. The slip-stick effect, a jerking and sliding, which may cause enormous noise development is prevented. More about SUSTARIN® C GLD 350 (POM)

Durostone® fasteners

With their high corrosion resistance and electrical properties, our Durostone® fastener offer a long service life, while their low density (between 1.9 and 2 g/cm³) makes it possible to save weight when building your nacelles. More about Durostone® fasteners

Labyrinth seals

Labyrinth seals of SUSTAMID 6G (PA 6G) for the rotor bearing are resilient against lubricants, provide high dimensions stability and thus permit reliable minimisation of the lubrication loss in the long term. More on SUSTAMID 6G (PA 6G)

Optamid® Pulleys

Pulleys made of our high-performance plastic Optamid® (PA 6G) have already been used successfully in cable lifts having traction sheaves for more than 45 years. Optamid® deflection rollers are always coloured yellow, provided with quality bearings and are quick and easy to install. Our services also include a computation of the load and bearing life.

The use of Optamid® deflection rollers in cable lifts has been approved by leading global testing authorities and our deflection rollers have approvals and certificates for global use.

Optamid® deflection rollers are available in roller diameter sizes of 65mm to 650mm and widths from 40mm to 178mm. This permits the use in MRL lifts, standard lifts and even heavy-duty systems and special systems. Of course, we also manufacture deflection rollers made of Optamid® having other dimensions according to customer requirements.
