Rolling bearings are the main type of bearings used in fans. Various types of bearings have their own advantages and disadvantages, but as long as they are properly designed and maintained, the fan can run smoothly.

The application characteristics of the fan industry are continuous and high-speed operation, easy heating of bearings, and extremely strict requirements on bearing noise. In response to the operating requirements of the fan industry, Yuxi 3Y Bearings has developed a series of special bearings for fans using special designs. It not only meets the fan industry's requirements for bearing noise, but also greatly improves the service life of bearings on fans, and can produce high-temperature resistant and high-precision bearings according to customer special requirements.

Main causes of fan failure (excessive bearing temperature rise, noise)

The shaft and rolling bearing are installed crookedly, and the front and rear bearings are not concentric;

The bearing clearance is too small, and there is no clearance after installation;

The bearing box vibrates violently;

The lubricant is of poor quality, contains impurities, dust, dirt or insufficient filling;

The tightening force of the bearing box cover and seat connecting bolts is too large or too small;

During the heating process of the bearing, the demagnetization is not clean or there is oil stain;

The surface of the bearing roller and the inner ring raceway are bumped.
