# 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? **

(Consider radial factor = 0.55, Thrust factor = 2 & application factor = 1.5?*- Published on 19 Oct 15***a.** 69.448 kN
