Yes, things will bind up without the roller. As Kevlar has said and done, there are cheap solutions to this instead of purchasing the whole regulator assembly. I picked up a pack of nylon wheels for a sliding glass bathtub door at home depot. It was about $3-4 and works fine. WAY cheaper than a new assembly
Can you post the part number of the wheels you used ? Since many people have a Home Despot in their vicinity, it might be handy to have the exact item.
A few questions:
How well do your wheels fit inside the track (tight or sloppy fit) ?
How did you fasten the new wheel to the scissor arm ?
I used similar rollers that I found on the net (#25389 - Roller, Wardrobe Door, 1" Wheel, 1/4" Offset (sold for $3.82 per pair)

While the roller diameter was only about 1 mm too small, the size of the hole was perfect for a 5/16" x 18 NC bolt that I used to replace the original press fitted pin. The one problem with this particular wheel was that they were too thick for the track, so I had to thin them down a little before they would slide into the track.
Also, the 5/16" bolts I used were pretty specific in that they have a 1/4" shoulder. The shoulder acts like a spacer and stops the bolt from tightening against and thus pinching the wheel. Ideally I would have used the same bolt, but with a fine thread, unfortunately they are not readily available.
I'd be interested in the details of your method. While my method is pretty good, I think there are a few things that could be made simpler, not the least of which is having to order hard to find rollers on the net.
Thanks !
