NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) today announced that its high-performance railway axle bearings have been selected for the E7 and W7 Shinkansen trains of the Hokuriku Shinkansen Line, which began operations in March 2015.
Railway bearings are important safety-critical components. They have a direct influence on the safe operation of railways and must comply with the highest safety requirements. In addition, they face the critical challenges to being compact and light in order to save energy and reduce impact on the environment. Shinkansen trains in Japan carry many passengers safely over long distances. The bearings selected for the Shinkansen trains must be highly efficient and durable and must pass strict quality controls.
