Roller identification

If I had understood the "dimples" had a function in holding the wheel in the door, I would have chosen the other wheels, though from the drawing they didn't look as precise a match as the ones I chose. I had no idea the dimples served a purpose.

Hopefully there is someone available to compare this wheel so we have an answer soon. The door didn't slide well in the middle when we tried the new wheels, but curiously did slide nicely at both ends of the track. We think we resolved that today with steel wool on the track. Just corrosion. How strange that it slid perfectly on old wheels until recently, when one old wheel broke and then it didn't slide at all, and we then found Swisco and you know the rest of the story.

So, the remaining frustrating problem is the wheels fall right out when you try to rehang the door unless they are blocked with masking tape. And since the door is extremely heavy that is a nightmare.
Look forward to hearing from you.

So are you telling me that the 81-148 is a different size in every respect than the sample old one from our home that I mailed to you? I was under the impression that with the dimples, it is a better match than what was previously sent to us. The ones we have work, except they fall out of the track due to flat surface and no dimples.
