Brake disks

We engage in the design and manufacture of forged steel brake disks that are used on coaches in high-speed trains such as Japan's Shinkansen bullet train. Forged steel brake disks have several distinct advantages over conventional cast iron disks. These advanced features include high wear resistance and prevention of cracks in sliding surfaces caused by heat loads at high speeds. Due to their superior durability, forged steel brake disks are used extensively for Japan's bullet trains . Forged steel brake disks are applied in various ways. Along with being attached at the wheel, some brake disks are installed in braking systems attached at the center of the axle.
