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.
What's the Applications of the R2AZZ Bearing?
The R2A ZZ bearing, as an imperial miniature deep groove ball bearing (with an inner diameter of 3.175mm, outer diameter of 12.7mm, and thickness of 4.366mm),as an imperial deep groove ball bearing, is widely used across various fields due to its high precision, high-speed capability, and sealing performance. Below are its primary applications:
