Ball Bearing Cooling Fan Difference? Cooling Fan bearing we have oil bearing, hydraulic bearing, double ball bearing, now most customers will choose the ball cooling fan, so we look at the ball cooling fan is different? Double Ball bearing adopts the form of rolling friction, several tiny steel balls in the bearing rotate around the axis, which makes the friction small and no oil leakage, and is characterized by stable operation and suitable for continuous 24 hours use, the service life is longer than the oil and hydraulic, the ball bearing will be more durable, more efficient, the noise compared to be small very right, do not use lubricating oil, so the performance and oil than to be more stable, so we recommend that high-speed fans choose the ball cooling fan, but the cost of the ball bearing is higher than that of the oil, so the price is higher. That is, Dongxing Yue's brief introduction of the difference between the ball bearing cooling fan and a good ball bearing cooling fan is very important. It can not only make the equipment run normally, also can extend its service life, the work efficiency also increases, if you want to know more radiator fan knowledge can pay attention to us.
