      Brief introduction for wind turbine brake pads:

       

      FRK980 is a cooper based sintered friction material facing for dry running applications. A special combination of alloy particle and copper gives high friction coefficient and smooth engagement. The performance is similar with MD550 from Miba Company. FRK980 is produced by pressing and sintering. It has the following advantages: high temperature resistance, very smooth engagement, high wear resistance, high and stable level of friction coefficient, negligible wear of mating material, easy replace, and safety. FRK980 is for brake system in  wind turbine, high speed train, highly loaded clutches. Now, we have many clients all over the country. We can process according clients drawing.
