A certain application requires a ball bearing with the inner ring rotating, with a design life of 26 kh at a speed of 425 rev/min. The radial load is 2.5 kN and an application factor of 1.2 is appropriate. The reliability goal is 0.9. Find the multiple of rating life required, XD, and the catalog rating 10 with which to enter a bearing table. Choose a 02-series deep-groove ball bearing from Table 11-2 and estimate the reliability in use. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
