What are the differences in the application of different types of deep groove ball bearings in industrial equipment?

Different types of deep groove ball bearings have differences in design and material, which leads to their respective focuses in industrial equipment applications. I will categorize them based on size specifications, structural design, and special materials, and explain the differences in their applications in industrial equipment. 
Deep groove ball bearings can be classified into different types based on their size specifications, structural design, and material properties. Their applications in industrial equipment vary significantly. From the perspective of size specifications, the outer diameter of micro deep groove ball bearings is usually less than 28mm and is often used in small and precise instruments, such as the rotating mechanism of the stage in an electron microscope. With its small size and high precision, it can achieve flexible rotation of small components and ensure precise focusing of imaging; while large deep groove ball bearings have an outer diameter of several hundred millimeters and play a role in the swivel bearings of port cranes, bearing huge radial, axial loads and overturning moments, ensuring the long-term stable operation of the cranes. 
In terms of structural design, deep groove ball bearings with dust covers or sealing rings are suitable for industrial environments with a lot of dust and oil. For example, in the crushers of mining machinery, these bearings can effectively prevent impurities such as mineral powder and crushed stone particles from entering, reducing wear and extending service life. Open deep groove ball bearings are often used in equipment with high heat dissipation requirements and clean working environments, such as the rotor support of high-speed motors. Because they have no sealing structure, they can reduce frictional heat during operation and improve motor efficiency. 
The applications of special material deep groove ball bearings vary as well. Ceramic deep groove ball bearings have characteristics such as high temperature resistance, corrosion resistance, and low density, and are often used in the fuel pumps of aircraft engines. Even in environments with high temperatures, high pressures, and fuel corrosion, they can still maintain stable operating performance. Stainless steel deep groove ball bearings are widely used in food and beverage production lines and medical equipment. Their excellent rust prevention and corrosion resistance properties comply with hygiene standards and will not cause pollution to products or the human body.
