There are many practical applications where we will use bearings. So what raw materials are commonly used in domestic bearing brands? Domestic bearing brands are generally made of high carbon steel, which is also known as bearing steel. Bearing steel contains five characteristics, the first is fatigue resistance. Under the function of cycle time load, the bearing surface will be easily fatigued or damaged, which will crack and fall off. Therefore, bearing steel must have high fatigue resistance. compressive strength. The second is the anti-wear performance. The bearing will roll friction, which will cause damage to the bearing parts. Therefore, in order to better maintain the precision of the bearing, the steel must also have precision firmness and prolong life. The bearing steel must also have excellent wear resistance. damage performance. The third is strength, which is also an important requirement for bearings. The strength of the bearing will indirectly affect the compressive strength, wear resistance and elastic limit of contact fatigue. Ultimately, bearing steel must have both excellent anti-rust treatment performance and production and processing performance, which is also to prevent bearing parts and finished products from being corroded and rusted during production, processing, storage and application. In addition to the above five points, bearing steel must also meet the requirements of non-metallic materials with less impurities, external surface defects meeting the standard and the surface carburized layer not exceeding the standard concentration value. As a domestic bearing brand, it was established in 1985 and has a history of 36 years. It covers an area of ​​25 acres. The company has passed the ISO9001 quality management system certification and obtained the provincial high-tech enterprise certification. The company was listed on the New Third Board in 2016, and the annual report is disclosed twice a year. It has standardized operation and good development prospects. It can provide you with continuous and stable supply capacity and perfect after-sales service.
