rolling bearing caps?

[trainfan2]

I saw in modelrailroader befor these trucks that have actual rolling caps. Walthers has them pg.280 kato 381-31602 . Has anyone used them? if so how well do they roll.and would they be worth the effect.

Genesis trucks have rolling caps, they are mounted to then ends of stub axle.

I have a few and they look good and roll good. I'd certainly get them if I didn't have to pay extra for the privilege.
