Requirements for Bearings in Air Purifiers

Air purifiers have specific requirements for bearings:

Moderate Speed Operation: The rotational speed is not extremely high, with approximately 2,500 RPM being sufficient.

High Sound Performance: There is a very high requirement for low noise operation, similar to the sealed motors used in air conditioners. The bearing must be exceptionally quiet.

Long Service Life: The bearing should support long-term operation without frequent maintenance or replacement, ensuring reliable performance over an extended period.


What's the Performance Features of R2AZZ Bearings ?

1. High Load Capacity: Designed for heavy radial, axial, or combined loads in demanding industrial and automotive applications.

2. ​Low Friction Design: Reduces energy consumption and enhances operational efficiency.
3. ​Durability: High wear and corrosion resistance, ensuring long service life.
4. ​Adaptable to Harsh Environments: Withstands extreme temperatures (-40°C to 150°C) and resists dust/moisture.
5. ​Quiet and Smooth Operation: Precision engineering minimizes noise and vibration.
