A shaft shown in the figure is proposed as a preliminary design for the application of gear
reduction process The effective centers of the gears for force transmission are shown. The
dimensions for the bearing surfaces (indicated with cross markings) have been estimated. The
shaft rotates at 900 rev/min, and the desired bearing life is 12kh with a 98 percent reliability in
each bearing, assuming distribution data from manufacturer 2. Use an application factor of 1.2.
(a) Obtain a Basic Load Rating for a ball bearing at the right end.
(b) Use an online bearing catalog to find a specific bearing that satisfies the needed Basic Load
Rating and the geometry requirements. If necessary, indicate appropriate adjustments to the
dimensions of the bearing surface.
