LanYu Bearing about the impact of checking 6 types of bearings on their use

L&Y Bearings is already well-known in Shandong because our company specializes in the production of double-row angular contact ball bearings. We have been carefully researching product technology for more than ten years, and our customers are also spread all over the country and abroad. L&Y senior research experts share our more than ten years of technical experience with friends who care about and support the development of L&Y Bearings. We hope that everyone will continue to support L&Y Bearings and continue to care about L&Y Bearings. In this article, we will focus on the impact of the calibration of angular contact ball bearings on their use.

Wear failure is one of the common failure modes of various types of bearings. According to the wear form, it can usually be divided into the most common abrasive wear and adhesive wear.

The judgment of whether the angular contact ball bearing is available is mainly based on the degree of bearing damage, mechanical properties, importance, operating conditions, and the period until the next overhaul. If there are the following defects, it can no longer be used and a new thrust ball bearing must be replaced. There are cracks or gaps on any of the inner ring, outer ring, rolling element, and cage.

The shaft parts of machine tools, especially the spindle, are generally assembled into one with the thrust ball bearing and rotate at a very high speed, which sometimes generates very high heat. If this phenomenon is not eliminated in time, it will cause the angular contact ball bearing to overheat, and the temperature of the corresponding parts of the machine tool will rise and cause thermal deformation. In severe cases, the spindle and tailstock will not be at the same height, which will not only affect the accuracy and processing accuracy of the machine tool itself, but also burn the bearing.

Rated fatigue life refers to the total number of revolutions of a group of bearings of the same model, which are operated under the same conditions, and 90% of the angular contact ball bearings do not have peeling caused by rolling fatigue.

When the speed is constant, the total operating time is often used to represent the rated fatigue life. When studying the life of thrust ball bearings, fatigue life cannot be considered only, but also several use limits should be considered based on the performance that the bearing should have. For example, the grease life of grease-lubricated bearings. Noise life, wear life, etc., according to different uses, the use limit standards are different, so most of them are pre-selected empirical limits.

Therefore, it is difficult to know the real cause of the damage by only investigating the damage of angular contact ball bearings. However, if you know the use of the thrust ball bearings, the use conditions, the structure around the bearings, and the situation before and after the accident, combined with the damage state of the bearings and several reasons, you can prevent similar accidents from happening again.

When the angular contact ball bearing rotates, the raceway surfaces of the inner and outer rings are in rolling contact with the rolling elements, so the running track is the dark side. It is not abnormal for the running track to be attached to the raceway surface. From this, the load conditions can be known. Therefore, when disassembling oil-free bearings, please pay close attention and observe the running track of the raceway surface.

The author of the above article is an expert from a professional manufacturer of double-row angular contact ball bearings, based on his many years of research on double-row angular contact ball bearings and other 3056 bearing series. In the future, there will be more high-quality news and technical knowledge about double-row angular contact ball bearings.
