Radial ball bearings are a key component in modern industrial equipment. Its main function is to support the rotating workpiece of mechanical equipment, reduce the frictional resistance during its fitness movement, and ensure its rotation accuracy. So what are the characteristics of the raw material bearing steel of the radial ball bearing? The following is a summary for everyone: Bearing steel characteristics: 1. Contact fatigue limit; under the influence of cycle time load, the contact surface of radial ball bearings is prone to fatigue damage, that is, cracking and falling off, which is also the main damage situation of bearings. Therefore, in order to extend the service life of the bearing, the bearing steel must have a very high contact fatigue strength. 2. Wear resistance; After the radial ball bearing works, not only rolling friction occurs between the throwing ring, rolling elements and cage, but also rolling friction occurs, which makes the bearing parts continue to be damaged. In order to improve the damage of bearing parts, maintain the firmness of bearing precision and extend the service life, bearing steel should have very good wear resistance. 3. Intensity; Intensity is one of the important qualities of bearing quality, which directly affects contact fatigue strength, wear resistance and elastic limit. The strength of bearing steel in use must reach HRC61~65, which enables the bearing to obtain relatively high contact fatigue strength and wear resistance. 4. Anti-rust treatment performance; In order to prevent the radial ball bearing parts and finished products from being corroded and rusted during production, storage and application, the bearing steel should have good anti-rust treatment performance. 5. Production and processing performance; during the production process of radial ball bearing parts, many cold and heat treatment processes are required. In order to meet the requirements of small quantity, high efficiency and high quality, bearing steel should have good production and processing performance. For example, cold and hot forming performance, grinding performance, cutting performance, etc. In addition to the above basic requirements, bearing steel should also meet the requirements of proper composition, average value of external structure, less inclusions of non-metallic materials, conformity of external surface defects, and the surface decarburization layer not exceeding the standard concentration value. Only when the torque is accurate can the rotation be stable! This article is from Co., Ltd., a manufacturer of radial ball bearings for 37 years.
