» Spherical roller bearings in fans

Feb 15, 1997· For spherical roller bearings, the minimum load can be considered to be 2% of the bearing’s dynamic capacity. Generally fan appliions with rotating shafts and stationary loads have bearing fits with the inner ring tight on the shaft to prevent fretting and the outer ring loose in the housing to accommodate axial thermal expansion of the shaft.

» 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
