Hi everyone, I have been designing a small desktop PCB mill, for which I intent to use SFU1204 ballscrew. I have 2 choices for the ballscrew supports, both from Chinese manufacturers on Aliexpress - FF10/FK10 with normal radial bearings or FF10/FK10 with angular contact bearings. Normally, I would go for the angular contact version, but I have had very bad experience with CNC parts there and don't trust the sellers will deliver. And unfortunately I can't afford the quality stuff from the likes of HIWIN and NKS. So, is it possible to replace the radial bearings with angular contact ones myself? I tried to find the bearing size for FK10 and FF10 supports, but all I know is that the I.D. is respectively 10 and 8 mm. If anyone has this information, please share it. Thanks
