Axle Products for Railway Rolling Stock

Technical strengths accumulated over many years, and high reliability

• Using technical strengths accumulated over many years, we manufacture high-performance axle products that account for almost all the wheels and axles in Japan.
• Axles (including wheels, axles, brake disks, drive unit mechanisms, and joints) can also be manufactured for high-speed rail transport such as the Shinkansen.

High-quality products realized with an integrated manufacturing process

• We manufacture high-quality wheels of superior microcleanliness and dimensional accuracy.

A production system established in North America.

• We have acquired Standard Steel LLC, the top U.S. maker of forged railway wheels and axles -- a company with a history of more than 200 years in the business. This move enables us to efficiently supply wheels to overseas customers.

Railway bogies that improve riding comfort and safety

Seeking complete riding comfort
Safety and assurance in running performance
Providing a full range of products and services, from design to manufacturing to evaluation

• Nippon Steel & Sumitomo Metal railway bogies are designed with a focus on providing complete riding comfort.
• Shinkansen bogies running at 300km/hr were the first in the world to be fitted with an active suspension system and pneumatic spring tilting system that we developed.
• A steering bogie has been developed to suppress noise and wear for safe and secure running of subway trains.
• Using an integrated system for design, manufacturing, and evaluation, we supply bogies to meet customer needs.

World's highest-quality rail products

• Reduction in total cost by being the world's hardest, straightest, and longest lived.

The highest degree of hardness in the world realizes a high degree of economy.

• Our rail products boast the highest degree of hardness in the world, realizing superb life cycle cost.
• Particularly, the "HE rail" has high wear resistance and high resistance to surface damage, making for long life and reduced grinding, which in turn realizes improved economy.

We can manufacture very straight rails in 150m lengths.

• Our independently developed universal rolling machine enables us to manufacture straighter rails.
• We can offer rails that have a high degree of straightness, such as rails for high-speed trains.

We can correct deviations from the horizontal axis and the vertical axis using our own universal rolling machine.

We can manufacture clean rails of uniform quality.

• We manufacture rails from iron ore using a coherent process, resulting in highly durable rails of uniform quality.
• Compared to the use of an electric furnace, our manufacturing process results in high-purity, high-quality rails.

【We manufacture rails using a coherent process right through from the blast furnace stage, resulting in clean products of uniform quality.】
