Sneaky,
The bearings you linked to are very much like the lazy susan bearings. They are used in a design that has two mating faces separated by the bearing with a shaft the same diameter of the inner diameter of the bearing. Other bearings then are required to maintain side loading. Check McMaster Carr for some bearings that might be more suitable for your purpose. In many designs, the shaft is cut so that the bearing pushes against an area of larger diameter on the shaft. The inner wheel bearings in your car are an example.
