Bearing No. CB209Z-Angular contact ball bearing-Vacuum Pump Bearing
Features
-
1. High speed:
The vacuum pump needs to reach a high speed during operation, so the bearing is required to have good
high-speed performance to adapt to the high-speed working environment,
2. High temperature resistance:
Since a large amount of heat is generated during the operation of the vacuum pump, the bearing is required
to have good high-temperature resistance to ensure normal operation in a high-temperature environment.
3. Accuracy and stability:
The vacuum pump has high requirements for accuracy and stability, so the bearing is required to have high
accuracy and stability to achieve precise axial and radial positioning
4. Long life:
The service life of the vacuum pump bearing has an important impact on the maintenance and replacement
cost of the vacuum pump, so the bearing is required to have a long service life.
5. Low friction and low noise:
In order to reduce the energy consumption and noise of the vacuum pump, the bearing is required to have a
low friction coefficient and noise level.
