So, let's go ahead and think about drawing what that would look like in terms of the radial probability distribution.

Radial loading is the amount of weight placed vertically above the axle. Sitting on a trike places an axial load on the bearings. The drawing below is a cross-sectional view of a radial bearing.

The drawing process for producing the part is completed in one operation, and a hole for machining use is pre-punched to control the magnitude of radial stress.
