In general, the hardness of ceramic bearings is higher than that of bearing steel bearings, so ceramic bearings have stronger hardness.
Ceramic materials are commonly used in the manufacturing of bearings, including alumina ceramics, silicon nitride ceramics, etc. These ceramic materials have good hardness and wear resistance, which can provide higher durability and longer service life compared to traditional bearing steel materials.
In addition, ceramic bearings also have advantages such as low friction coefficient, low thermal expansion coefficient, and excellent corrosion resistance, making them widely used in some special industrial applications.
However, it should be noted that ceramic bearings are relatively more vulnerable to impact and vibration. Therefore, when selecting bearings, it is necessary to consider them comprehensively based on specific usage conditions and application requirements.
