5cm Silent DC Cooling Fan, 3pcs XIN RUI FENG 5V Ball Bearing, 3pcs XIN RUI FENG 12V Ball Bearing, 3pcs XIN RUI FENG 24V Ball Bearing

1. All-copper movement, strong air flow, durable, high speed stability2. Pure copper wire movement, high temperature resistance, stable operation and long life3. High-strength and thickened fan blades. The fan blades adopt a one-time injection molding process, which is not easy to deform and break. The unique design of the fan blades makes the contact area larger, the air volume is larger, and the heat dissipation effect is good.4. The outer frame is made of PVC plastic, which is resistant to high temperature and can withstand physical impact to a certain extent, effectively protecting the motor and fan blades5. Scope of application: heat dissipation of mechanical equipment6. Applicable temperature: -10 to 60 degrees Celsius7. Bearing: double ball/oil8. Motor power: 12V: 1.56W, 24V: 3.84W9. Voltage: 5V/12V/24V10. Current: 12V: 0.13A, 24V: 0.16A11. Air volume: 12V: 9CFM, 24V: 9.1CFM12. Speed: 12V: 4500R/MIN, 24V: 5000R/MIN13. Material: PVC plastic14. Product life: 60000 hours15. Size: 50x50x10MMDifference:- 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 noiseSpecification: Package Weight One Package Weight 0.25kgs / 0.56lb One Package Size 8cm * 8cm * 5cm / 3.15inch * 3.15inch * 1.97inch Qty per Carton 118 Carton Weight 30.00kgs / 66.14lb Carton Size 39cm * 39cm * 24cm / 15.35inch * 15.35inch * 9.45inch Loading Container 20GP: 730 cartons * 118 pcs = 86140 pcs40HQ: 1695 cartons * 118 pcs = 200010 pcs
