Replacing a 30 year old sliding door roller assembly

A quick learner says:
This roller assembly is from a sliding glass door which must be at least 30 years old. I cannot find a manufacturer's name anywhere on the unit. I removed both roller assemblies and found the bearings shot. I do not see this particular roller assembly, or anything close, on your website. No store in this town carries, or has seen this style.

I have attached pictures. The assembly is 1-7/8" high (at the larger rounded portion) by 2-1/8" wide, with a width of 11/16". The roller is 1-1/2" diameter, and 5/16" wide, concave.

Any assistance would be greatly appreciated!

The new replacement roller has arrived and is ready for purchase, see 81-242. Double check the dimensions of your roller to the 81-242 product picture.
