1-11/16" dia Nylon Concave BB Wheel

I am looking to replace this part which is from an older patio door. The wheel is 1-1/2" diameter, 3/8" wide and the hole in the center is also 3/8". I could just do the wheel if not the whole part, but i can't seem to find one that has a steel bearing and nylon/plastic outer wheel part. Thank you ... (cont.)

Trying to find this roller (2) . There is no adjustment on this and just a drift pin that holds everything together. if you need more information please let me know. Don

I have a patio door with an unusual roller. The height is adjusted with an inserted aluminum piece that rolls over an angled shim. The shim (or wedge, or cam, or whatever it's called) has a flat side with Do you have a replacement for this wheel assembly?

We have 12 sliding doors that have become difficult to slide because of flat spots and wheels no longer turn. The doors are 12-13 years old in an island environment. Do you sell such a door part?

Closet door is brass and glass. Not sure of the plastic roller is replaceable or if I need a new unit altogether. Case is appox 0.58" wide, 2.32" long (looks to be adjustable), and 1.05" tall. Unsure of roller diamter but has a marking of C-Co on it if that helps.
