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 307 bearing operates under the following schedule of loads and speeds:
Radial load of 450 lb at 1000 rpm for 30% of the time
Radial load of 1000 lb at 300 rpm for 15% of the time
Radial load of 2000 lb at 100 rpm for 55% of the time
The inner ring rotates; loads are steady. Find the rating life at 8 hours per day for this bearing.
