A radial, deep grove ball bearing is specified from a manufacturer’s catalog based on a L10 life of 106 cycles. The bearing has a basic load rating of 2,500 N and is to be used in an application where the design radial load is 350 N and the axial load is zero. What is the predicted life (hours of the bearing if the inner race of the bearing rotates at 1,800 rpm? A.70 B. 3,400 C. 200,000 D. 160
