The bearing you've linked is an LM16UU, that translates as a bearing for a 16mm round rod, normally used for z-axis rails in some 3D printer types, not a bearing that will fit on the outside of a 1 inch/ 25.4mm tube.

Admittedly their naming convention is poor, But this will work just fine. I have attached the data sheets the manufacturer provided me. Sorry for the poor image quality.

wouldn't that be the outer diameter of the bearing casing, not the inner diameter for the linear rod the bearing can go on?

Nope! Here you can see the "dr" number is 25.4 mm or 1 in.

And here you can see "dr" is the bore diameter:

Edit: For extra measure. Here's a clipping from the manufacturer?/wholesaler? :

Nice. I guess that's the difference of the "LMB" bearings. Looking forward to seeing a pic of it assembled.
