The rolling contact ball bearing are to be selected to support the overhung countershaft. The shaft speed is 820rpm. The bearings are to have 99% reliability corresponding to a life of 19,000 hours. The bearing is subjected to an equivalent radial load of 2 kN. Determine the basic dynamic load rating of the bearing in kN from manufacturer's catalogue, specified at 90% reliability. Hint: Get the life of the bearing corresponding to 99% reliability first using L = 60NLH
