Oil bearing is usedSliding frictionSleeve bearing, uselubricating oil As a lubricant and drag reducer,Low operating noise during initial use, The manufacturing cost is also low, but this kind of bearing is severely worn and has a long lifeMore There is a big gap between ball bearings. And this kind of bearing has been used for a long time, Due to the oil seal(It is impossible to use high-end computer radiator products Oil seals, usually ordinary paper oil seals),Lube will gradually Volatile, and dust will enter the bearing, causing the fan to rotate Slow down,Problems such as increased noise, and serious problems due to bearing wear Cause the fan to be eccentric and cause severe vibration. These phenomena occur, or Open the oil seal and refuel, or you can just buy a new fan after phasing out. |
