Problem $11\mathrm{.}023-$ Calculation of effectlve radial load

A $02-$serles single$-$row deep$-$groove ball bearing with a $30-mm$ bore $($see Tables $11-1$ and $11-2$ for specifications$)$ is loaded with a $2-kN$ axial load and a $5-kN$ radial load. The inner ring rotates at $300re\frac{v}{m}in.$

Problem $11\mathrm{.}023.$b $-$ Prediction of life for a bearing

Determine the predicted life $($In hours$)$ that this bearing could be expected to give in this application with a $96\mathrm{.}0$ percent rellability.

The predicted life that this bearing could give in this application with a $96\mathrm{.}0$ percent reliability is hours.
