A certain application requires a ball bearing with the inner ring rotating, with a design life of 25 kh at a speed of 350 rev/min. The radial load is 2.5kN and an application factor of 1.2 is appropriate. The reliability goal is 0.90. Find the multiple of rating life required, xD, and the catalog rating C10 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.
