What are the surface treatment methods for deep groove ball bearing 60 series

In the modern machinery manufacturing industry, the surface treatment technology of bearings plays a vital role in their performance and service life. Cixi Bao li Bearing Manufacturing Co., Ltd. uses a variety of mechanical and chemical surface treatment processes in the production of Deep Groove Ball Bearing 60 series to ensure the performance of the product under high load and harsh environmental conditions.

Mechanical surface treatment process
Mechanical surface treatment is the basic process for the manufacturing of Deep Groove Ball Bearing 60 series, mainly including sandblasting, wire drawing, mechanical polishing and polishing. These processes can not only effectively improve the surface quality of the product, but also improve its fatigue resistance and wear resistance.
Sandblasting: This process uses the impact force of high-speed sand flow to clean the bearing surface, remove impurities such as oxide scale and rust, and form a matte pearl silver surface. This treatment method significantly improves the fatigue resistance and coating adhesion of the bearing surface, allowing it to maintain stable performance during high-load operation.
Wire drawing: The fine lines formed on the bearing surface through the grinding process not only enhance its decorative effect, but also enhance the texture of the metal. This treatment strikes a good balance between visual effect and functionality.
Mechanical polishing: The surface of the bearing is finely processed using polishing tools and abrasive particles, which significantly reduces the surface roughness and ultimately obtains a bright, flat surface. This high-gloss surface not only improves the appearance, but also helps reduce friction and extend the service life of the bearing.
Polishing: Using a special polishing wheel or belt, burrs and scratches on the bearing surface are removed to improve flatness and electroplating quality. This process ensures that the bearing performs better in subsequent treatments.

Chemical surface treatment process
In addition to mechanical treatment, Cixi Bao li Bearing Manufacturing Co., Ltd. has also introduced a variety of chemical surface treatment processes to further improve the corrosion resistance and wear resistance of the Deep Groove Ball Bearing 60 series.
QPQ treatment: This process immerses the bearing in two salt baths of different properties, and forms a composite infiltration layer through the penetration of multiple elements. This treatment significantly improves the wear resistance, fatigue resistance and corrosion resistance of the bearing surface, ensuring that it can still operate stably in harsh environments.
Chrome plating: A layer of metallic chromium is plated on the surface of the bearing to form a passivation film, which significantly improves the hardness and wear resistance. The hardness of hard chrome plating can reach 1000HV, which allows the bearing to maintain good performance after long-term use.
Blackening/blueing: By heating the bearing to an appropriate temperature, a blue or black oxide film is formed on its surface. This film not only improves corrosion resistance, but also enhances anti-friction performance, providing a more solid guarantee for the use of the bearing.

Electrochemical surface treatment process
The electrochemical surface treatment process forms a protective coating or conversion film on the surface of the bearing through the principle of electrolysis. Cixi Bao li Bearing Manufacturing Co., Ltd. uses technologies such as anodizing and electrochemical nickel plating in the production of Deep Groove Ball Bearing 60 series.
Anodizing: This process increases the thickness of the oxide layer on the surface of the bearing through electrolysis, thereby improving its hardness and wear resistance. This treatment method effectively extends the service life of the bearing and meets the needs of high-intensity work.
Electrochemical nickel plating: A uniform nickel layer is plated on the bearing surface, which significantly improves corrosion resistance, hardness and wear resistance. The electrochemical nickel plating layer has good bonding strength, ensuring reliability and durability under various working conditions.
