(a) Design a journal bearing for following data used for Machine Tool application :
Load W= 12 kN
Journal speed =1000 rpm
Assume suitable data (diameter of journal, l/ d ratio, lubricating oil, and operating temperature etc) and design completely the journal bearing. Make conclusions if any.
(b) Select a suitable ball bearing for the head stock of lathe machine rotating at 1000 rpm. The bearing is subjected to radial load of 7000 N and a thrust load of 3500N. The machine is to work for 6 hours/day for a service life of 8 years. Suggest the diameter of spindle for which bearing can be used.
