The ones I've found are stamped with USA. I've bought new CC bearings and they're made in Tiawan. Bugs me. The HEIMs I've found are Lord only knows how old and still serviceable. Roland stated the basic #RF12-22-14. Most of the ones I'm finding are suffixed AP. Roland also mentioned PP, ZZ, etc. Those suffixes stand for different styles, I think, such as open, sealed on one side, sealed on both sides. Maybe different applications, too. The AP's are sealed on the outside, open on the inside. Enjoy the weekend! F.
