Why Rifle Bearing?

Rifle bearing fan types offers a number of advantages against ball bearings and sleeve bearings fans.
Rifle Bearing and Ball Bearing both have a life expectance of about 50,000 hours. Sleeve bearing has a life expectance of over 20-30,000 hours.
Most people will know that Ball Bearing is noisier than Sleeve Bearing, Rifle Bearings offers the life span of ball bearings and the silent operation of Sleeve bearings. So rifle bearing provides the best noise and the best life span. It's the best from both worlds

FN121-BL

lolz are u selling it dude?

or do u know where to get it?

"Rifle Bearing"
is that new technolgy?

Rifle Bearing = greater life span (50,000 hours) + silent operation

i thought normally sound come from the blades?...

it comes from the motor as well... the dc motor will sound loud if its lubricant dried out... normally the sound isnt comes from blade, high cfm fan sound normally comes from vibration and huge airflow hitting on radiator fins or heatsink fins...

the fan looks nice but the static pressure is low...

last time coolermaster case fan also using rifle bearing. but after that no more using already. i donno why. i got a few cooler master fan which using rifle bearing which quite durable compare to sleeve bearing.

Then use Yate Loon Mid speed

use 38mm fan la haha

another commercial scam

rifle bearing is almost the same as sleeve bearing... the design is different.... or we can say it is an improvement of standard sleeve bearing....
this difference will make the bearing more durable than conventional bushing/bearing....

quite ok the spec n the rifle bearing quite new..huhu..

i thought bushes n bushing are the same...
as far as i know bush use to fit hole...
use if the male female hole is off tolerance...
just a guess
