Patio Door Wheels

Hi There,

I work for a glazing company and we are repairing multiple patio door wheels in an apartment building. I have attached pictures of the wheels we removed out of one of the doors and I was looking for a replacement and I can't find one that matches.
The dimensions are - 1" Tall, 2 5/8" Long, and 9/16" Wide and the wheel has a diameter of 1 1/8" and is nylon (metal would be ok too though)

Hoping you can help - thanks!
