60 series precision deep groove ball bearing

Specification The life of a rolling bearing is defined by the number of revolutions (or the number of hours of work at a certain speed): the bearing within this life should have preliminary fatigue damage (flaking or defect) on any of its bearing rings or rolling elements. However, no matter in laboratory test or in actual use, it can be clearly seen that the bearing has the same appearance under the same working conditions, but the actual life is very different. In addition, there are several different definitions of bearing "life", one of which is the so-called "working life", which means that the actual life that a certain bearing can reach before damage is caused by wear and tear, and damage is usually not caused by fatigue, but Caused by wear, corrosion, seal damage, etc. In order to determine the standard of bearing life, the bearing life and reliability are linked. Due to the difference in manufacturing accuracy and material uniformity, even the same batch of bearings of th…
