Select a suitable ball-bearing subjected to following loads:
Radial load of 600 kgf at 150 r.p.m. for 25% of time.
Radial load of 750 kgf at 600 r.p.m. for 20% of time.
Radial load of 200 kgf at 200 r.p.m. for 55% of time.
The loads are steady . The outer ring remains stationary. The bearing has to bare an expected average life of 2500 hours. The shaft diameter can be adjusted to the bearing selected. The data given below may be used.
