Ball Bearing Surfaces

Main Question or Discussion Point

Do the balls in a bearing actually touch both races? If so, how does the thing turn? Won't the balls be moving in different directions at each race, and therefore dragging against one?

There are two answers. In an ideal bearing, there is no sliding. In all real bearings, there is some sliding, but it is due to the deformation or angular mislaignment.
