Part Identification Request: Vintage Sliding Door Roller Assembly (Nylon Wheel)

Question

I am seeking a replacement for an older, vintage-style sliding door roller assembly.
Unfortunately, the original assembly is heavily damaged, making it impossible for me to determine the exact original the wheel diameter. The housing dimensions are indicated in the attached photos.
Could you please help me identify a compatible replacement part? If the exact vintage model is discontinued, do you have a modern substitute or a "roller and axle kit" that might work with this specific housing?
Thank you for your expertise and assistance.
Best regards,
Lee

Hi Lee,

Your sliding door roller appears to be a match for the 81-139 Sliding Door Roller. Take a look over the dimensions below to determine if this is the replacement you need. Compare them to confirm this will be the right fit in the door.

This is available in both a nylon wheel and a metal wheel.
