Numerical - Basic dynamic capacity of bearing, given radial & axial force, rating life
Q. A deep groove ball bearing rotating at 1200 r.p.m. is subjected to radial and an axial force of 2000 N and 1500 N respectively. What will be the basic dynamic capacity of bearing if 20,000 hours is the rating life?
