Requesting help with a single wheel sliding glass door roller assembly

A home owner from East Lake, FL says:
Good afternoon, I was hoping you could help me identify a proper replacement for this glass door slider. On the wheel it reads Saunders Engineering. Is this something you carry?

Hi there!

Saunders Engineering Corp is no longer in business, but take a look at our 81-047 roller. Double-check your dimensions to see if this matches up to your original hardware. Let us know what you think.
