The formation and development of the world bearing industry has roughly gone through three stages
The first stage, the initial stage of the world bearing industry, is from the end of the 19th century to the beginning of the 20th century. At that time, although the invention and application of bearings had been for some time, the industrial production of bearings had just started from scratch and was quite naive. The main features are:

The standard was formulated early, and the quality grade of bearing was determined by measuring the vibration acceleration value of bearing rotation, which was divided into three quality grades: Z1, Z2 and Z3 from low to high. At present, domestic bearing manufacturers are still using the vibration acceleration value to measure the advantages and disadvantages of bearings, which simply reflects the fatigue life of bearings.

Due to the differences in manufacturing accuracy and material uniformity, even the same material and the same size of the same batch of bearings, used under the same working conditions, have different service life. 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 rated life of the bearing.
