That does look interesting for the price. I remember seeing years ago some very expensive linear bearings (possibly also SKF) with built-in encoders. Anybody make those for reasonable prices now? https://www.linearmotiontips.com/space-saving-integrated-guide-linear-encoder-from-thk/ -- Ralph __

Mentioned on the IRC. SKF (and maybe others) make standard 62-series bearings with a built-in encoder. The PPR isn't huge but for measuring (for example) motor speed they look handy. Also potentially a good fit for some lathes, just because the through-hole is large, even if not used as a bearing.
