Get Price2008-1-15u2002·u2002Once the fan bearings are back in operation, monitor them for changes in vibration and operating temperature. Bearing lubricant can retain heat, causing operating temperatures to rise. If you detect high temperatures, change out the old grease, thoroughly clean the fan bearings and housings, and refill with the initial grease filling.
Get PriceCommon Causes of Vibration in Centrifugal Fans. Ever since centrifugal fans have been manufactured they have been subject to vibration related problems. These problems range from simple unbalance conditions caused by mass variations on the fan rotor to much more complex issues related to shaft alignment, bearing fatigue, or resonance issues.
Get PriceFan Bearing. Thus in a fan bearing, where a unidirectional load is transmitted from a rotating shaft to a stationary bearing housing, the shaft would be manufactured from an alloy steel, which would retain its shape, whilst the bearing housing would be lined with 'white' metal or 'babitt', which would take up the shape of the shaft as shown in Figure 10.1.
