Try PDF Linear technology company Ltd. They are actually Taiwanese bearings imported into china. Seems the taiwanese make most of the linear bearings.

I tell you thru experience of using plenty that they are perfectly fine and worth every penny thou the small difference in price between 15mm and 20mm makes the 20mm the better option due to bearing size providing better footprint and giving more clearence for ballscrew on Z axis.

If you want to see a picture of them let me know I have some 20mm here.!
