Selection of common bearing types

With continuous improvement and perfection, a huge family of oil-impregnated bearings has been able to meet the needs of mainstream applications. Currently, the most widely used hydraulic fan has a lifespan between 30,000 and 50,000 hours, which is fully capable of meeting the needs of ordinary applications. The mute effect is obviously better than that of a ball fan, so users do not need to blindly pursue a ball fan when purchasing a fan. Moreover, the technical difficulty of the ball fan is relatively high, and the price is also more expensive. However, for users who are looking for longevity, they might as well buy a double-ball fan and nano-ceramic bearings. For users who are pursuing ultra-quiet, it is better to buy a magnetic levitation fan, but the disadvantage is that the process is more difficult and the price is more expensive.
