Bearing rating life

- Jan 03, 2019-

Due to the difference in manufacturing precision and material uniformity, even the same material, the same batch of bearings of the same size, used under the same working conditions, the lifespan is not the same. If the statistical life is 1 unit, the longest relative life is 4 units, the shortest is 0.1-0.2 units, and the ratio of the longest to the shortest life is 20-40 times. 90% of the bearings do not produce pitting, and the number of revolutions or hours experienced is called the bearing rating life.
