What are ceramic bearings used for?
Compared with other types of bearing, the most important characteristics of ceramic bearings are high-temperature resistance, high speed, and corrosion resistance. Below we introduce its use environment based on these advantages:
1. High-temperature resistance and cold resistance: ceramic ball bearings are less affected by thermal expansion and contraction, and can work in environments with large temperature differences.
2. Fast speed: Under the same size, the weight of the ceramic is relatively light, and the speed can be increased by 40%. Thus the service life is greatly extended.
3. Corrosion resistance: it can work in special fields such as cola, gasoline, chemical raw materials, etc.
Usually, what we call a ceramic bearing is a ball bearing of ceramic material. If ceramic balls are used instead of steel balls, the bearings are ceramic wheel bearings. The main materials of ceramic bearings are Si3N4, ZRO2, and SIC. With the rapid development of the industrial age, people have also invented the full ceramic ball bearing, which makes it faster and has greater bearing capacity. At the same time, ceramic bearings skateboard is also a special application.
