Determine the C10 value for this application.
The C10 value for this application is
kN.
A certain application requires a ball bearing with the inner ring rotating, with a design life of 26 kh at a speed of 455 rev/min. The radial load is 2.5 kN and an application factor of 1.2 is appropriate. The reliability goal is 0.92. 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.
The design load on a ball bearing is 413 lbf and an application factor of 1.2 is appro-
priate. The speed of the shaft is to be 300 rev/min, the life to be 30 kh with a reliability
of 0.99. What is the C10 catalog entry to be sought (or exceeded) when searching for a
deep-groove bearing in a manufacturer's catalog on the basis of 106 revolutions for rat-
ing life? The Weibull parameters are xo = 0.02, (0 – xo) = 4.439, and b = 1.483.
