CUI Japan expands its lineup of DC axial fans and centrifugal blowers.

CUI Devices has added a new series of 13 products, including the smallest 20mm square DC fan, to its lineup of DC axial fans and centrifugal blowers, enabling us to better meet a wider range of customer needs. We offer three types of bearings, including our unique omniCOOL system, with sizes ranging from 20mm x 20mm to 172mm x 152mm. Additionally, each option includes a tachometer (pulse) signal and PWM signal output.
<Sleeve>
Advantages:
High impact resistance, most affordable
Disadvantages:
Slow start due to friction, requiring more drive energy
Uneven wear may occur depending on the mounting angle
Gas generated from friction may remain in the bearing, solidify, and cause blockage
Short lifespan
<Ball>
Advantages:
Quick start and low drive energy due to less friction
Springs between bearings suppress rotor tilt, allowing use at any angle
Long lifespan
Disadvantages:
Inferior impact resistance, relatively high noise, higher cost
<omniCOOL>
Advantages:
Less friction and accumulation of lubricants
Price comparable to sleeve bearings
Improved lifespan compared to sleeves
