The difference between ceramic bearings and ordinary bearings during operation
There are some differences between ceramic bearings and ordinary bearings during operation, mainly reflected in the following aspects:
1. Material: Ceramic bearings use ceramic materials (such as aluminum oxide, silicon nitride, etc.), while ordinary bearings usually use metal materials (such as steel). Ceramic materials have the characteristics of high hardness, high wear resistance, and low friction coefficient, while metal materials have good toughness and plasticity.
2. Friction and wear performance: Ceramic bearings have lower friction and wear due to their low friction coefficient and high hardness, which can reduce energy loss and extend service life. In contrast, ordinary bearings have higher friction and wear.
3. Corrosion resistance: Ceramic materials have high corrosion resistance and good stability to acids, alkalis, chemicals, and humidity. Ordinary bearings may be more sensitive to corrosive substances and humidity.
4. Temperature stability: Ceramic bearings have good high-temperature stability, can work in high-temperature environments, and maintain good performance stability. Ordinary bearings may experience deformation, softening, or wear at high temperatures.
5. Weight and lightweight design: Due to the low density of ceramic materials, ceramic bearings are relatively lightweight, which helps to achieve lightweight design, reduce load, and improve overall efficiency. Ordinary bearings are usually heavier.
6. Manufacturing and assembly requirements: The manufacturing and assembly requirements of ceramic bearings are relatively high, and the processing and assembly process is relatively complex, requiring higher process requirements. Compared to this, the manufacturing and assembly of ordinary bearings are relatively simple.
It should be noted that ceramic bearings also have some limitations, such as higher costs and lower load-bearing capacity for impact and vibration. Therefore, when selecting bearing types, a comprehensive evaluation needs to be conducted based on the specific application needs and considerations.
