Horii Trains excel in safety and punctuality, and regular maintenance is indispensable to achieving these goals. Since the operating environment differs from country to country and region to region, bearings must be durable enough to last over the maintenance period required by each country. In recent years, the number of skilled railcar maintenance workers has been decreasing due to declining workforces, and the need for bearings that are easy to maintain has been increasing as a trend in the sector.
Tomida Since 1932, when NSK developed tapered roller bearings for the axles of gasoline-powered trains run by Japan’s national railroads, the company has grown together with customers especially through the development of the Shinkansen bullet trains. NSK bearings have been used in all types of Shinkansen models since the first Shinkansen, the 0 Series, began operation in 1964. NSK bearings are also used in the Tokaido and Sanyo N700S Shinkansen, which is the newest model that began commercial operation in July, 2020. Our newest Shinkansen bearings are lighter and feature higher lubrication performance, improvements that we achieved through a rigorous iterative design and development process.
