Tables $11-2$ and $11-3$ are based on manufactures $2.$

A shaft with rolling bearings and loads is shown in Sketch $1.$ The bearings are mounted such that

both the axial and radial forces caused by the external loads are absorbed$.$ For bearing at position

$B$ the geometry is cylindrical rotating the inner race, so that only radial load can be absorbed$.$

The full axial thrust load $500$ N is thus taken up by a series $02$ deep$-$groove ball bearing at

position A$.$ The shaft rotates at $1200re\frac{v}{m}in,$ and the desired bearing life is $15$ kh with a $96$

percent reliability in each bearing, assuming distribution data from manufacturer $2$ in Table $11-$

Use an application factor of $1\mathrm{.}2.$

For series $02$ deep$-$groove ball bearing at position $A,$ obtain.

$($a$).$ The equivalent radial load that will be experienced by this particular bearing.
