  • The Importance of Ball Bearing Fan | NMB Technologies

    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.
