Bearing on the high-speed bearings is high-speed rail transport, with high speed, radial load and wear resistance, usually of more than 160 km per hour in EMU the bearings on the high iron-bearing.
Although the country has been able to produce with independent intellectual property rights EMU high-speed railway vehicles, but is still applied in domestic production of high speed railway bearings in the blank. Currently the EMU imported bearings bearings are all used. Therefore it is imperative to vigorously develop a high speed railway bearings localization is.
