How to achieve high precision of flange ball bearings

Flange ball bearings have played an important role in many industrial applications with their excellent high-precision performance, and their precision design is the key factor to achieve this performance. The bearing adopts an integrated flange outer ring design, which not only simplifies the installation process, but also significantly improves the accuracy of axial positioning. This innovative design enables accurate axial positioning without additional positioning devices during installation, greatly improving work efficiency.

In terms of raceway design, flange ball bearings are precisely calculated and optimized to ensure smoothness and low friction during rotation. The geometry, dimensional tolerances and surface roughness of the raceways are strictly controlled. These factors together meet the needs of high-precision applications and ensure the stable performance of bearings under various working conditions.

The choice of materials is also crucial to the high precision of flange ball bearings. Generally, high-carbon chromium bearing steel is used as the main raw material. This material not only has high hardness and excellent wear resistance, but also has excellent mechanical properties, making it an ideal choice for manufacturing high-precision bearings. Before the raw materials are put into production, strict chemical composition analysis and mechanical property tests are required to ensure that they meet high-standard manufacturing requirements.

The manufacturing process of flange ball bearings relies on advanced processing technology and equipment. High-precision equipment such as CNC grinders, CNC milling machines and high-speed machining centers are widely used in the rough machining and finishing stages of bearings. These equipment achieve micron-level machining accuracy for key parts such as inner and outer rings, raceways and contact angles of bearings through precise CNC programming and advanced sensor technology. In the fine machining stage, ultra-precision grinding technology is used, combined with high-speed cutting and ultra-fine grinding tools, to further improve the machining accuracy and surface finish of bearings.

Heat treatment processes play an indispensable role in the high-precision realization of flange ball bearings. Through heat treatment processes such as quenching and tempering, the bearing material obtains the necessary strength and wear resistance while maintaining good toughness. During the heat treatment process, parameters such as heating temperature, holding time and cooling rate are strictly controlled to ensure uniform hardening of the inner and outer rings of the bearing and minimize deformation. In addition, the low-temperature tempering process is used to eliminate the residual stress generated during the machining process and prevent material deformation, thereby further improving the accuracy and stability of the bearing.
