8038 Mini Size Portable Smoke Extractor Fan

Common bearings for  mini size portable smoke extractor fan are:ball bearings,oil-bearing.The ball bearing of the mini size portable smoke extractor fan changes the friction mode of the bearing,using rolling friction,there are some steel balls or steel columns in the middle of the two iron rings, and supplemented by some grease lubrication.This method more effectively reduces the friction between the bearing surfaces,effectively improves the service life of the fan bearing,and therefore reduces the heat generation of the radiator and extends the service life.The disadvantage is that this mini size portable smoke extractor fan process is more complex,leading to cost increases,but also brings higher working noise.The oil bearing of the mini size portable smoke extractor fan is a sleeve bearing using sliding friction,and the lubricating oil is used as a lubricant and drag reducer.Can be said to be one of the most common bearing technology on the market,due to low cost,simple manufacturing,many products including well-known brands are still in use.The advantages of the mini size portable smoke extractor fan of this type of bearing are quiet,low noise and cheap in the initial use.
