Winders - that is interesting. I've never paid attention to which way any of this stuff goes, other than putting it together so it works rather than locks up. Of course, when I goof that up I know it right away, and redo it.

I have not bothered with the circle on the outer, nor differences with one end of the inner. I can't say as I have noticed any asymmetry in the cage (what I have noticed is that the brand new ones are looser on the balls than some of my collection of worn old ones were).

Occasionally I will reverse the whole assembly to get the wear to occur in a different spot, if it hasn't grooved anything. But that is different.

So what difference do these small markings and so on actually make, as the parts sure look symmetrical to me.
