No idea but SJS have a comprehensive selection of bearings and SA spares.

They might even be able to tell you if you contact them.
Edit: 3/16” (4,78mm) according to RJ on YouTube.

24 x 3/16" and 14 x 1/4". Very old hubs need 16 x 1/4".
Recent SA hubs have a plastic ball retainer/seal instead of the 24 loose balls. It is a rubbish design compared to the old labyrinth seal but is no doubt cheaper to make.
