  • Sleeve Bearings & Ball Bearings in Industrial Fans

    2021-6-5 · 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.

    2009-2-20 · One cause of fan failure is confusing the fixed and floating bearing positions. A typical fan has two bearings supporting the shaft. In most cases, the bearing exposed to the highest radial load should be fixed, or axially held, within the housing. Radial bearings generally perform better when the axial-to-radial load ratio is low.
