Dynamic axial load carrying capacity

Bearings with integral flanges on both inner and outer rings can support axial loads in addition to radial loads. The axial load carrying capacity is determined by the ability of the sliding surfaces of the roller end/flange contact to support loads. It is also influenced by the division of the rings and the type of lubrication. Operating temperature and heat transfer from the bearing also play a part.
Guideline values for the permissible axial load which can be applied to single row cylindrical roller bearings can be obtained from

Fap = C0/(40b)

where

Fap=maximum permissible axial load [kN]
C0=basic static load rating (→ contact SKF) [kN]
b=factor for mode of machine operation (table)
The values of the permissible axial load Fap obtained from the equation are valid for continuously acting constant axial loads and grease lubrication. Higher values can be allowed if oil lubrication is used. In case of doubt, please contact the SKF application engineering service.
