Applied with 160km/h urban rail train, the test speed is greater than 6200r/min, the application speed is ≥4100r/min, the maintenance period is 1.2 million kilometers, and the design life is 2.5 million kilometers.

The bearing design precision level reaches above P5

cage lightweight design

roller bearing optimizes ribs and roller base surface

ball bearing optimizes the tightness of the raceway

improves bearing performance

and realizes high-speed applications. Outer ring outer surface with insulation coating layer

effectively prevent the impact of high-voltage and high-frequency current on the application performance and life of the bearing.
