2021-5-19 · On average, a fan that operates for 50,000 hours will run continuously for over 5 years. The chart indicates that when temperatures ranged from 25-60° C, ball bearing fans on average outlasted sleeve bearing fans by 50 percent. When temperatures exceeded 70° C, ball bearing fans ran for 45,000 hours, while sleeve bearing fans became inoperable.
Get Price2017-1-30 · The lifetime of a sleeve bearing fan is often shorter than that of a ball bearing fan, however, if the temperatures are low within the application then similar lifetime expectancy can be achieved. So if the application generates low heat or has a short life span than a sleeve bearing fan can be considered.
Get Price2019-4-9 · Ball bearings are the standard by which other small-fan bearing systems are judged.
