Aoju Bearing

  We all know that bearings are a very common tool in the industrial field. So do you know the early bearing forms? The early form of linear motion bearings was to place a row of wooden poles under a row of pry plates. Modern linear motion bearings use the same working principle, sometimes with balls instead of rollers. The simplest swivel bearing is the bushing bearing, which is just a bush sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, which replaced the original bushings with many cylindrical rollers, each rolling element acting like a separate wheel.

  Under a certain load, the number of revolutions or hours experienced by the bearing before pitting occurs is called the bearing life.

The life of rolling bearings is defined by the number of revolutions (or the number of hours of work at a certain speed): bearings within this life should have initial fatigue damage (flaking or defect) on any of their bearing rings or rolling elements. However, no matter in the laboratory test or in actual use, it can be clearly seen that the actual life of bearings with the same appearance under the same working conditions is quite different. In addition, there are several different definitions of bearing "life", one of which is the so-called "operating life", which indicates that the actual life a bearing can achieve before failure is caused by wear, damage is usually not caused by fatigue, but Caused by wear, corrosion, seal damage, etc.
