XIN RUI FENG 12V Ball Bearing 6cm Quiet DC Cooling Fan

Description

1. Copper core motor, strong wind, fast heat dissipation, safe and durable
2. Low noise, long life, low energy consumption, large air volume, stable operation, fast start
3. High-strength and high-toughness fan blade, one-time injection molding, long service life, not easy to deform and break; not only has strong wind power but also effectively reduces noise
4. The outer frame is made of high-quality PVC plastic, which can withstand high temperature and withstand physical impact to a certain extent, effectively protecting the motor and fan blades

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-impregnated 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
