Key Points for Selecting Fan Bearings: Avoiding Noise And Aging Issues

‌  Earlier I made a video about fan bearings. A viewer commented: "Don't all modern fans use sleeve bearings now? Are deep groove ball bearings still used?"Today we'll address this.‌

‌  In fan operation, bearings are critical components that directly determine noise levels, operational lifespan, and performance. While both sleeve bearings and deep groove ball bearings serve as core components supporting blade rotation, significant differences exist in their structure and performance characteristics - ultimately impacting real-world user experience.

  Sleeve bearings are optimal for cost-sensitive applications requiring low rotational speeds, such as desk fans and wall-mounted fans (ideal for short-term use or budget-constrained scenarios). Conversely, deep groove ball bearings deliver persistently quiet operation and extended service life, making them superior for continuously operated appliances like ceiling fan lights, pedestal fans, and tower fans, particularly in noise-sensitive environments such as bedrooms and studies.‌

‌  Selection criteria must account for operational duty cycles and environmental requirements to prevent suboptimal bearing choices that cause progressive noise escalation.

  Selecting the correct bearing enables decade-quiet fan operation. Kenda Bearings employ ZV4-grade precision grinding, achieving 0.2μm raceway smoothness that generates friction sounds quieter than falling leaves. Our proprietary sealing technology locks specialized grease within, preventing solidification or lump formation - even after five years of continuous use.‌

‌Third-party testing confirms: Fans equipped with Kenda Bearings exhibit only a 2 dB(A) noise increase after 3,000 hours of continuous operation, dramatically lower than the industry-average 15 dB(A) surge.‌
