Based on many of the pictures and CAD models I've seen, the "standard" way to create them is to cut a pocket all the way thru your 2 x 1 x 1/8 siderail, and then slide a bearing block into the pocket from the side. Once in place, the bearing block gets a plate bolted to it from both sides to hold the block captive in the slot while allowing it to slide front to back.
It seems a simpler approach would be to cut the same pocket in the siderail, but then slide a 1.75 x .75 bearing block in the siderail from the end. This would just fit inside the inside dimensions of the tube, and would eliminate the need for the sideplates and fasteners.
I can see a downside to the simpler approach, and that is that you need access to the end of the tube you're installing the block in. That doesn't seem like that big of a deal. I would think the two would be comparable from a weight standpoint. Is there another downside to this approach that I'm missing?

A long, long time ago (before my time even) 973 used to do this.
The problem is the inside of extruded tube is all over the place dimensionally, so this blocks end up being really finicky.
