Patio Door Wheels

We don't sell anything exactly like this, unfortunately. However I did I pick out two rollers from our catalog that you may want to consider. 

See our 81-270 roller, which has that lip at the end of the housing like yours seems to have. My major concern, however, is that it has a wheel diameter of 1-1/2". 

The other roller is our 81-024. This has a 1-1/8" wheel, which is closer to the 1" diameter of your original. 

Finally, take a look at the 81-223 and the 81-310 axle kit. If your roller housing is in good shape you might need just to replace the wheel and axle. 

I can't guarantee that any of these products will work for you but they are our best options.
