Wheels, together with the axle, are the most important components that literally support the safety of railway rolling stock from beneath the floor. Today, maximum train speeds can exceed 300km/h, and the acceleration and braking performance of subway and urban trains are improving. All this makes the service conditions of wheels more and more severe. However, wheels must be absolutely reliable at all times.

We are the only manufacturer of railway wheels in Japan. By providing high-quality wheels for many years, we have won the trust and high esteem of customers. At the same time, we have been able to respond to the demands of the times with ongoing technological innovation in both manufacturing and design, and by developing wheels with increasingly high performance. Our new technologies are highly regarded at home and abroad, and our wheels are widely used throughout the world.
