  High-speed Ball Bearings

  Usually we name a rolling bearing with a Dmn value of more than 1.0X106mm.r/min as high speed ball bearing. " Dm" is the average diameter of the rolling bearing, and " n" is the speed of the inner ring. The centrifugal force has great influence on the life and strength of rolling bearings when they are moving at high speed. Therefore, the weight of high-speed rolling bearings is often reduced to improve the high speed perfor...

  Life And Load Rating

  When bearings raotate , the inner and outer rings and rolling elements are constantly loaded . This produces material fatigue and eventually bearing failure . The total number of revolutions before a failure occurs is called the basic rating life . Life of individual bearings varies considerably , even if they are of the same size , same material , same heat treatment and are under the same operating conditions . Stati...
