With over 60 years of experience they are providing seals to a variety of industries. At Trelleborg the R&D department is constantly exploring new materials, new ideas and new innovations. It is challenging to ensure seal life and performance in hydraulic applications. Not only must leak-free operation be achieved, but high pressures, temperatures and transverse forces must be sustained.

As a distributor of Trelleborg Sealing solutions we strive to ensure you only use the best seal available for your application. Although we are able to deliver any seal type required we at HPS are specialized on the hydraulic seals for the brake systems in the wind power industry. Trelleborg has been involved in the wind power industry from the beginning. As a rapidly evolving industry, wind power is subject to constantly innovating technologies.

The rotor brake, yaw brake and the rotor locking system have critical safety related functions within the wind turbine. Inside, the sealing solutions must provide an absolute reliability of function over years of operation be it in cold climates or in the heat of the desert.

The seals we provide must:
- Demonstrate reliability, durability and perfect leakage control
- Operate at pressures up to 30 MPa / 4,350 psi
- Provide temperature resistance in extremes of temperature, both high and low
- Work with the lowest friction and wear possible
- Offer longest possible service life - industry target is 20 years.

Any seal solution you need, HPS is sure to find a right fit for your application. Highlighted here are a few of the most important seals for wind power brake applications we have on stock. For Yaw and Rotor brake applications we have a large stock available for the 90, 110,120 and 125 diameter pistons. Thus ensuring a fast and easy delivery to your location
