Gearboxes, traction motors, axle sets, and

door closing systems, all of these include

bearings in rail vehicles. The main requirement for these bearings is reliability.

NSK bearings for traction motors are designed to achieve longer service life, safety, and high reliability. These bearings

must meet requirements for high radial,

axial, and impact resistance, high speed,

and long and maintenance-free operating

times. Therefore, NSK uses superpure bearing steels. Both the inner and outer rings

undergo thermal dimensional stabilisation

and very rigid cages are used.
