Customized manufacturers tell you, what are the two major parameters of bearings? Friends who don't know yet, come and learn together, the custom manufacturer will solve your doubts, and friends who understand new knowledge every day will grow taller~ Under the action of a certain load, the number of revolutions experienced by the bearing before pitting occurs or hours, called bearing life. 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 initial fatigue damage (peeling or defect) on any of its bearing rings or rolling elements. However, whether in laboratory tests or in actual use, it can be seen that the actual life of bearings with the same appearance under the same working conditions is very different. In addition, there are several different definitions of bearing 'life', one of which is the so-called 'working life', which indicates the actual life that a bearing can achieve before failure is due to wear, 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 related. Dynamic load rating In order to compare the bearing capacity of the bearing against pitting corrosion, when the rated life of the bearing is specified to be one million revolutions (106), the maximum load that can be supported is the basic dynamic load rating, expressed as C. That is to say, under the action of the rated dynamic load C, the reliability of this kind of bearing working for one million revolutions (106) without pitting failure is 90%. The larger the C, the higher the bearing capacity. Co., Ltd. was established in 1985, focusing on the production of precision ball bearings. It has been a professional bearing custom manufacturer for 35 years. Production of various types and specifications of angular contact ball bearings, deep groove ball bearings, short cylindrical bearings, tapered bearings, single row angular contact ball bearings, double row angular contact ball bearings, paired bearings, Automobile bearings and non-standard bearings of various technical requirements, etc.
