There are many practical applications where we will use bearings. So what raw materials are domestic bearing brands commonly made of? 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 contact surface of the bearing 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 and rub, 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 have an indirect impact on the contact fatigue strength, wear resistance and elastic limit. Ultimately, bearing steel should have both good antirust performance and processing performance, which is also to prevent bearing parts and finished products from being corroded and corroded during processing, storage and use. In addition to the above five points, bearing steel also needs to meet the requirements of less non-metallic inclusions, conformity of external surface defects, and the carburized layer does not exceed the specified concentration. 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. The operation is standardized and the development prospect is good. It can provide you with continuous and stable supply capacity and perfect after-sales service. (/gczcpp.html)
