Product review (4 stars): Works well enough, except replacement is a China-made bearing ...
Works well enough, except replacement is a China-made bearing instead of the NSK (Japanese quality) bearing original equipment.  Hope it lasts 'cuz it's a PITA to replace!

FWIW, the bearing is a 6206Z - you can just buy a quality Japanese or American bearing and pop into the metal holder.  If I hadn't already bought the replacement, I would have done that.
