UC206 Structural Features:

Keyscrew design: Two keyscrews, angled at 120°, are used to secure the shaft. This facilitates installation and removal, and accommodates varying shaft diameters to a certain extent. However, the mounting requirements are limited by the vibration range of the environment.

UC206 outer spherical surface design:

The bearing's outer diameter is spherical, suitable for use with housings with spherical inner bores. This provides excellent self-aligning performance and automatically compensates for installation errors and shaft deflection, enabling the bearing to better adapt to varying operating conditions.

UC206 sealing type:

usually has a sealing structure, such as double-layer seal or triple-lip seal, which can effectively prevent dust and impurities from entering the bearing, thereby improving the service life and reliability of the bearing and is suitable for relatively harsh working environments.

UC206 Material:

Bearing rings are generally made of high-quality bearing steel, such as GCr15, which offers high strength, hardness, and excellent wear and corrosion resistance, ensuring stable bearing performance over long periods of operation. Rolling elements, typically steel balls, are also made of high-quality bearing steel. Precision machined and ground to achieve high precision and surface quality, they reduce rolling friction and improve the bearing's rotational flexibility and transmission efficiency. Cages are typically stamped or injection-molded from steel sheet, isolating the rolling elements, guiding their motion, and evenly distributing the load.

UC206 Manufacturing Process:
It undergoes multiple precision machining processes, including forging, turning, heat treatment, grinding, and assembly. The forging process ensures the material's excellent microstructure and mechanical properties; the turning and grinding processes ensure the dimensional accuracy and surface finish of each bearing component; the heat treatment process enhances the material's hardness and wear resistance; and the assembly process ensures the bearing's overall quality and performance.
