When choosing high-speed ceramic bearings, there are several factors that need to be noted:
1. Material selection: ceramic bearings are usually made of silicon Boron nitride (Si3N4) or aluminum oxide (Al2O3) and other materials, which have excellent hardness, wear resistance and corrosion resistance. Select appropriate ceramic materials based on specific application requirements and working environment.
2. Bearing design: For high-speed applications, choosing the appropriate bearing design is crucial. Generally speaking, angular contact ball bearings or deep groove ball bearings are commonly used in high-speed applications. Angular contact ball bearings can withstand high axial and radial loads and have high speed capabilities.
3. Accuracy level: High speed applications require high bearing accuracy to ensure smooth and reliable operation of the bearings during high-speed rotation. The accuracy level of bearings is usually classified according to ABEC levels (such as ABEC-5, ABEC-7, etc.), with higher levels indicating higher accuracy.
4. Cooling and lubrication: During high-speed operation, bearings generate significant frictional heat, while ceramic materials have relatively poor thermal conductivity. Therefore, it is necessary to consider a good cooling system to control bearing temperature. At the same time, appropriate lubrication is also very important, which can be achieved through internal lubrication of bearings (synthetic grease) or external lubrication (such as oil lubrication systems).
5. Bearing sealing and cleaning: For high-speed bearings, the closed design and magnetic cleaning system can prevent dust, particles and other impurities from entering the bearing, and keep the bearing clean and in normal operation.
When choosing high-speed ceramic bearings, it is recommended to consult Shanghai Anding Yitai technical engineers, who can provide more detailed suggestions and guidance based on specific application needs. 136-2180-8094
