A picture would helpIf you mean a grooved wheel will be running along it, I see two ways1: screw through the back into the rodDrill holes along the rod and C-channelTap the holes in the rod, and screw them togetherYou can blind drill and tap, or throughYou might want to get saddles made for the rod2: weld bolts to the backside of the rod, and fasten through the c-channel.
A drawing of what you want would helpOtherwise your description is not clear enoughI can picture all sorts of things and if I give you an answer it will be for what I imagined in my mindFirst off, does the bar need to be free to rotate? If so then you're not attaching the bar to the channelYou'll want to mount the bearings to the channelNow, depending on what sort of bearings you have you'll need the appropriate clamps or bearing race mounts to mount it to the channelWelding sounds like you don't want the bar to rotateIf that's the case, welding is not going to workUnless you know someone who can magically weld steel to aluminumBut another possibility in my mind is you want to put the bar across the openingI know you said the flat side, so it's hard to imagine how a bearing will run across the barThe more I think - the more I realize I could spend hours trying to guess at what you wantA little more detail or a drawing would helpI make tons of drawings and post them to Flickr (dot) com and post linksThat way when I describe something complex I can include a drawing to help clarify what I'm suggestingTry that.
