2) A shaft is designed with two 6305 bearings. At bearing 1, the radial load is 20 lb, and at Bearing 2, the radial load is 40 lb. What is the expected life of EACH bearing assuming a reliability of 97%? What is the reliability for BOTH bearings together?

An 02-seris single-row deep-groove ball bearing with a 90 mm bore (C0 = 62 kN, C10 = 95.6 kN) is loaded with a 4.34 kN axial load and a 10 kN radial load. The inner ring rotates at 600 rpm (v=1). What is the FaC0? Should X1/Y1 or X2/Y2 be used to caculate the equivalent radial load? Determine the equivalent radial load experienced by this bearing. What is the bearing’s in-use reliability, assuming a design life of 2*10^8 revolutions and an application factor of 1.2?

Select an angular contact ball bearing to carry a radial load of 336lb at a shaft speed of 1800 rpm for 5500 hours. Anapplicationfactorof1.2isappropriate. Use a reliability of 96%.
