how are balls placed in roller bearings?

Question by : how are balls placed in roller bearings?
I always wanted to know how the balls of roller bearings were placed into the two races?

They are not just placed in there and the inner race place after the balls, there has to be some forceful actions.

Does anyone know how this is done?

Thanks,

One way is the shape of the two races that goes together one way with clearance for the balls (roller bearings use rollers so we are talking about ball bearings) then a retaining ring is added.
But another way is to chill the inner race to contract it and heat the other race to expand it and machine them in the first place so the balls fit when they are expanded apart from each other and close in and trap the balls when at the same temperature.
