The weight of the components supported by the bearings, together
with external forces, generally exceed the requisite minimum load. If
this is not the case, the bearings must be subjected to an additional
radial load or axial preload.

Symbols C = basic dynamic load rating [kN] († product tables)
e = calculation factor († product tables)
F a = axial load [kN]
F r = radial load [kN]
F rm = minimum radial load [kN]
P = equivalent dynamic bearing load [kN]
P 0 = equivalent static bearing load [kN]
Y, Y 0 , Y 1 , Y 2 = calculation factors († product tables)
1) When determining the axial load F a , refer to Calculating the axial load for bearings mounted singly or paired in
tandem († page 812).
