Chapter 11, Problem 11P

11-8 to 11-13 For the bearing application specifications given in the table for the assigned problem, determine the Basic Load Rating for a ball bearing with which to enter a bearing catalog of manufacturer 2 in Table 11-6. Assume an application factor of one.

Problem Number Radial Load Design Life Desired Reliability
11-8 2kN 108 rev 90%
11-9 800 lbf 12 kh, 350 rev/min 90%
11-10 4 kN 8 kh, 500 rev/min 90%
11-11 650 lbf 5 yrs, 40 h/week, 400 rev/min 95%
11-12 9 kN 108 rev 99%
11-13 11 kips 20 kh, 200 rev/min 99%

An 02-series ball bearing is to be selected to carry a radial load of 8 kN and a thrust load of 4 kN. The desired life Lp is to be 5000 h with an inner-ring rotation rate of 900 rev/min. What is the basic load rating that should be used in selecting a bearing for a reliability goal of 0.90? Hints: Rating life is 1(10°) revolutions, Weibull parameters of rating lives are x, = 0.02,0 = 4.459, b = 1.483 respectively.
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. %3D
A certain application requires a ball bearing with the inner ring rotating, with a design life of 25 kh at a speed of 400 rev/min. The radial load is 3.5 kN and an application factor of 1.5 is appropriate. The reliability goal is 0.90. Find the multiple of rating life required, Xp 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.
