We have 7 bearing assemblies along our turret gear which you can see if you look closely on page 16. Each bearing assembly consists of 3 ball bearings in the following order: a large bearing, a small bearing, and a large bearing (I do not know the exact bearing size). Each bearing is separated by a small shim and is lined up along a 10-32 screw with a locknut threaded at the bottom of the screw. The locknut is not tightened to its fullest extent in such a way that as the two large bearings sit upon the top and bottom of the plate connecting the two sides of the superstructure, they are able to slide along the plate's surface in addition to the small bearing with can rotate freely as it contacts the inner edge of the plate.
