Fan Industry

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

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

1.The installation of the shaft and rolling bearing is skewed, and the front and rear bearings are not concentric;

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

3.Severe vibration of the bearing box;

4.Poor lubricant quality, containing impurities, dust, dirt, or insufficient filling;

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

6.During the heating process of the bearing, the demagnetization is not clean or there is oil stains;

7.There are bumps and scratches on the surface of the bearing rollers and the inner race raceway;
