A quick learner from Chicago says:
Looking for parts replacement, these are from a heavy sliding glass door. Unable to find at local hardware store, please help.

I would look over our 81-129 and 81-262, one of these may be the hardware you're looking for.
A professional from CA says:
The wheel in 81-162 is very narrow. Probably meant for screens. It definitely will not fit on normal 1/4" rails. I bought a pair years ago and never found a good use for it. 81-129 is very common.
