Need glass door rollers.

A quick learner from Lahaina, HI says:
1-1/2" roller. Stamped on side of roller is DWB-98 S&S Bearing. Roller is plastic. Adjusting screw goes into threaded hole Photo shows where adjusting screw broke the hole. Any help is appreciated! Need a couple of them, maybe a few more but I haven't checked the other doors yet to see if they are the same. I may also need some track covers (Didn't know they existed!).

I don't know what you have from these photos, unfortunately. What you're showing me here is just the inside portion of a complete roller unit. There should be an outer housing still installed in the door. In order to ID a match, I need to see the whole assembly together. I will also need to know the width and height of the outer housing itself.

Finally figured how to get housing out (easy, once you figure it out...). Attached are photos of complete assembly. You can see manufacturer and other numbers. Housing is 1-1/2" high, 5/8" wide. Thanks you for your help!

Thanks! This looks like a dead ringer for our 81-258S. Check it out and let me know if you agree.
