Try Round Rail
HI,
I am making a CNC milling machine and am looking for chrome-plated, precision round bar for a linear guide , however I don't seem able to find anything. The closest I've got is stainless but that is not really hard enough to provide long life without wear. I've tried google and directly on ebay but nothing relevant seems to come up.
I must be searching for the wrong terms / words , can anyone suggest what I should be keying in to find this sort of bar?
Thanks for any ideas.
BTW I need 3/4" or 20mm bar at least 75mm long. Diameter can be in 18-20mm range.
This is the sort of thing I need, from a French supplier which seems rather dear, and he is only reselling chinese imports anyway. I wanted to find a similar thing on Bang-good or some other outlet but I'm drawing a blank.

Thanks but that seems to be more to do with skateboarding and wardrobes. Got me a couple of hits to Thomson bearings but not round bar.
Thanks for the suggestion.
Search for linear shafting.

Thanks Ger21. Shaft was indeed the key word I needed. That produces all the results I knew must be there but were not coming up.
Many thanks for the help.
Try Aliexpress. I have bought the SBU20 for my CNC Router and HGR20 for my CNC late. They work for me.
