CHAPTER 9 9.1. A ball bearing is subjected to a radial load of 2884pounds for 40% of the time and 1884pounds for the remainder of the load cycle. Speed is 1884rpm. Expected life is to be 10 years at 250 days per year and 6 hours per day. Calculate the minimum value of the basic load rating that the bearing must have. All loads are steady.

A 50 mm diameter pressure fed journal bearing is operating at 50 rev/s under a load of 5 kN giving a projected unit load of 2 MPa. Half journal length is l' = 25 mm, and radial clearance is c = 25 microns. Oil inlet temperature is maintained at 30 °C and average temperature is to be kept at 70°C. Viscosity of the oil used is then 12 mPa.s. What is the minimum required supply pressure [kPa] that maintains this...
