2)The single-row 02-series Deep-Groove ball bearing with a 55-mm bore is subjected to a 6-kN axial load and a 13-kN radial load. The inner ring rotates at 120 rev/min. (40 Points) a) Calculate the predicted life (in hours) that this Deep-Groove ball bearing could be expected to carry the applied load with a 99 percent reliability. b) Assume that a single-row 02-series Angular Contact ball bearing is required for this application and it should carry the same amount of applied equivalent load with the same realibility (99%) for 5000 h. Suggest a bore diameter for an Angular Contact bearing for this application. Given Data: -In order to check the specifications of 02-series single-row deep-groove and angular-contact ball bearing, see Tables 11-1 and 11-2) -If the inner ring rotates take V as 1, a = 3 for ball bearing -Application factor (ar)-1, Weibull parameters; xo=0.02, 0=4.459, b = 1.483 -Rating life (catalog life) of bearing is 1 million revolutions.
