To achieve high-speed rotation of 100000 revolutions, it is usually necessary to choose materials suitable for high-speed applications to manufacture micro bearings. Here are some common material choices suitable for high-speed rotation:
Angular contact ball bearings: For smaller sized micro bearings, angular contact ball bearings are typically used for high-speed applications. This type of bearing is usually made of high-speed steel (such as GCr15), which has good hardness and wear resistance, and can provide reliable performance at higher speeds.
Ceramic bearings: Micro ceramic bearings are also an ideal choice for high-speed rotation applications due to their high hardness and low friction characteristics. Aluminum oxide (Al2O3) and silicon nitride (Si3N4) are common ceramic materials that have excellent high-temperature stability and wear resistance, suitable for high-speed rotation.
High temperature alloy bearings: In applications that require high-speed rotation in high-temperature environments, high-temperature alloy materials can be considered for manufacturing bearings. These materials have excellent high-temperature stability and corrosion resistance, making them suitable for special industrial applications.
Suitable materials need to be selected based on specific application requirements and performance requirements. In addition, the optimization of manufacturing processes and bearing structures will also have a significant impact on high-speed rotational performance. Therefore, it is recommended to consult the bearing manufacturer or engineer when selecting materials.
