Difference:
- Ball bearing: the model is generally indicated by B; there are several tiny steel balls in the bearing that rotate around the axis in the form of rolling friction, so the friction force is small and there is no oil leakage. Features: long life, suitable for high speed fans
- Oil bearing: the model is generally indicated by S; it adopts a sliding friction sleeve, and the shaft of the fan blade uses lubricating oil in the sleeve as a lubricant and a drag reducer. Features: Resistance to external impact, low noise
