In the following problems, it is assumed that the bearing has but one row of balls. A working year will be taken as 250 days.
A ball bearing is subjected to a radial load of 2000 lb for 40% of the lime and 1000 lb for the remainder of the load cycle. Speed is 1760 rpm. Expected life is to be 10 years at 6 hours per day. Find the minimum value of the basic rating load C that the bearing must have. Loads are steady.
