  • Bearing Super Technology:Ultra-High Speed|Products ...

    2019-4-1 · As a bearing rotates at high speed, there is a large centrifugal force acting on the ball. Because of this centrifugal force, there is a large load on the outer race of the bearing that interferes with high-speed rotation. Also, a sufficient oil film cannot be maintained with conventional lubricating oil, so heat cannot disperse and the ...
