FAQ
The ball bearing brand was NSK bearing imported from Japan.
The warranty for ball bearing fan is 30,000 hours but sleeve bearing just 10,000 hours.
Ball bearing has 5-8 years lifetime,sleeve bearing has 2-3 years lifetime.
Ball bearing fan noise level won’t change for a long time term,but sleeve bearing fan noise level will grown as time goes on.
Sleeve bearing is cheaper than ball bearing fans.
