Thread: Profile v Supported Round Rail
Threaded View

Yes, that's "v" not "vs". Technically correct in this situation? Possibly not, but old habits die hard.
Anyway, the title says it all really. Over comparatively short distances (200mm of travel for any given point on a 200mm table, so estimating 400mm of rail) are there any specific advantages or disadvantages between the two?
For a vertical axis, will they both work as securely as each other?
Thoughts, opinions and wisdom welcome as always!
Edited to add: I've read elsewhere that for these small-size machine purposes, the difference between 15/20/25 profile rails is almost nothing. At this point I'm looking at the Hiwin rails from Zapp, if it's a matter of brand quality.
