Estimate the bearing life in hours for 90


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 3500 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 90% reliability. (See Figure P14.18.)
