Chapter 11, Problem 12P

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%
