The build is looking good! Always interesting for me to see older European equipment.

I think Tessen is saying the balls in the ball bearings could crush a little and not turn smooth anymore if too much side force it put on them. Also if they don't rotate very far each ball will wear a little groove of it's own into the races which is probably why you always see bushings used on heavy equipment. But that isn't to say that ball bearings won't work for you with the relatively light loads and low hours most models see.
