What Is The Rated Life

- May 21, 2018 -

Rated life: due to the difference in manufacturing accuracy and uniformity of materials, even for the same materials and the same size of bearing, the life span of the same bearing is different under the same working conditions. 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%, there is no pitting corrosion. The number of revolutions or hours experienced is called the rated life of the bearing.
