Two single-row 02-series angular contact ball bearings with inner ring rotation are to be selected by a student for her Capstone project from Table 11-2 to support a radial load of 3.5 kN and axial load of 1.25 kN. The desired total machine reliability is 95%. The desired life of the bearings is 1 year of continuous operation in a machine operating at 900 rpm with light to moderate impact. Use the "manufacturer 2" Weibull values from Shigley Table 11-6 and equivalent radial load factors from Table 11-1. Fully specify the smallest bore size for these conditions.

Determine the rated life and median life of the bearing. Use the design factors according to the attached table.
A single row deep groove ball bearing is operating at a speed of 2000rpm acted upon by a radial load of 10kn and thrust load of 8kn. The bearing is subjected to light shock load and outer ring is rotating. Determine the life rating of the bearing
