A No. 204 radial-contact ball bearing is used in an application considered to be lightto-moderate with respect to shock loading. The shaft rotates 1300 rpm and the bearing is subjected to a radial load of 1000 N and a thrust load of 250 N. Estimate the bearing life in hours for 99% reliability. n rpm No. 204 radial ball bearing F, = 1000 N, F,= 250 N 99% reliability Light-moderate shock loading L = ? hr life
