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 R2AZZ 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), is widely used in various fields due to its compact size, high-speed capability, and low-noise performance:
Widely used in micro motors, vibration motors, shaded-pole motors, and gear motors. Particularly suitable for applications with strict size and speed requirements, such as garden tool motors, drone motors, etc.
Used in injection molding machine accessories, winding machines, vulcanizers, laser engravers, and other equipment, supporting high-precision transmission.
Suitable for scraper machines, crushing equipment, mining machinery, and other industrial scenarios requiring moderate load-bearing capacity.
Used in optical instruments, testing equipment, encoders, and other devices that require low vibration and high stability.
Commonly found in camcorders, video recorders, hard disk motors, card readers, and other precision electronic devices, supporting high-speed operation.
Applied in dental drills, pharmaceutical mixing equipment, dialysis machines, and other medical devices, meeting the demands of sterile environments and high reliability.
Used in computer cooling fans, air conditioner motors, juicers, and more, providing quiet operation and durability.
Found in smart locks, robotic vacuum cleaners, 3D printers, and other smart home or office equipment.
Suitable for remote-controlled toys, model helicopters, fitness equipment, etc., enabling lightweight design.
