A shaft is loaded with a centre load of 7000 N between two bearings and an overhanging load of 4000N as indicated. In order to accommodate the load a Series 03 Cylindrical bearing is used for Bearing 1 while a Series 02 Deep Groove bearing is selected for Bearing 2. The application requires a lifetime of 30000 hrs at a speed of 750 rpm with a minimum reliability requirement of 98% for the shaft. Assume an application factor of 1.25 and specify suitable bearings to satisfy the requirements. Also indicate the overall reliability of the shaft assembly that can be expected. 7000 N 4000 N 300 300 300
