Seeking replacement rollers

A home owner from Battle Ground, Washington, USA says:
Hello,

This appears to be one of two rollers for my sliding glass door: I have no idea what brand it is, there are no embossed brand names, nor are there any stickers.

The bearings on these are completely shot. the box is about 3/4" thick, by 1 3/16" high. the roller is steel, and the outer diameter of the wheel is about 1 1/8", and the wheel outer surface is concave about 1/4" wide.

Note also there is an extra tab above the adjustment screw.

Thank you for your time, I appreciate your service.
