Sliding door trolleys

A home owner from San Diego, CA says:

I need to replace several trolleys on some sliding doors. The rubber 'tires' on the wheels have fractured. I have just purchased three replacements from you, but they are the wrong size.

The steel body of each trolley is 1 9/16" long and 9/16" wide. Each wheel including 'tire' is 7/8" in diameter. I had previously ordered the 23-176S, but they do not fit.

SWISCO product code 23-193, roller assembly, looks like a closer match.
