A207 series radial-contact ball bearing is loaded uniformly (without shock) as follows: • load is 8 kn at a speed of 1440 rev/min for 25% of the time; • load is 10 kn at a speed of 720 rev/min for 50% of the time, and • load is 20 kn at a speed of 2880 rev/min for 25% of the time. estimate the bearing life for a 90% reliability.
