I have a seized spaceway roller.
Any advice to free it up?

Not sure where this roller is of how you would do this...but.. looks like a steel shaft and roller in a steel carrier.
The steel surfaces corrode and the rust sits on the surface as an expanded layer.
What was a running clearance fit becomes an interference fit. Unless you dissolve the rust it will not free up.
I have had lots of derusting success with white vinegar..
Immerse and it comes off as a grey black sludge.
May need to clean the WD40 off first with white spirit so the vinegar can get to and wet the rust.
when free then WD40 again.

These rollers are made up from number of thick fibre washers. I free them off by removing the shaft and easing the washers off one at a time. If you are not bothered about originality you can make up a better roller by using a piece of rubber tubing over a new shaft (piece of 6" nail) then sliding a piece of stainless tubing over the rubber. You can then keep the original piece in your bedside cabinet and gloat over it at regular intervals. Hope this helps :roll:
