Design an appropriate bearing that will be ted to the end of the stepped shart. The shaft was then inserted in the gearbox and rotated at 225 revolutions per minute. The outer ring rotates during operation, and the bearing carries radial and axial loads of 8 kN and 5 kN, respectively. The bearing life cycle is 8 hours per day, 5 days per week, for 5 years, with a reliability factor of 96.5 per cent for the ensemble of bearings. Consider the application factor while designing the commercial gearing.

Question
Design an appropriate bearing that will be fitted to the end of the stepped shaft.
The shaft was then inserted in the gearbox and rotated at 225 revolutions per
minute. The outer ring rotates during operation, and the bearing carries radial and
axial loads of 8 kN and 5 kN, respectively. The bearing life cycle is 8 hours per
day, 5 days per week, for 5 years, with a reliability factor of 96.5 per cent for the
ensemble of bearings. Consider the application factor while designing the
commercial gearing.
a) Evaluate the equivalent radial load subjected to the bearing.
b) Design the appropriate 03 -series cylindrical roller bearing.
c) Designation of selected bearing.
d) Determine the reliability of the final selected bearing. Justify whether the
selected bearing is suitable for application with 96.5 % reliability.
