» What’s normal:The role of temperature in bearing
Feb 15, 1998· The standard grease in most fan bearings remains effective to an operating temperature of 180°F. If steady-state operating temperatures are higher than 180°F, consider using a grease with a synthetic base oil. Viscosity in a synthetic oil does not vary as much with temperature as in a standard mineral oil, and the rate of oxidation is much
Fan Bearing Types – Weighing the Pros and Cons | CUI Devices
Ball bearing fan designs use a ring of balls around the shaft to solve uneven wear and rotor wobble problems. Most fan motor designs have two bearings, one in front of the other, and these bearings are usually separated by springs. The bearings offer reduced friction compared to sleeve designs and the springs can assist with any tilt in the fan

Overhung Fan asselies Which bearing should be fixed and
Feb 20, 2009· 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.

Fan Bearing - an overview | ScienceDirect Topics
Fan 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.
