Sizing & construction of the 23-136 tricycle door hanger

A home owner from Athens, WI says:
Do the rollers of the 23-136 have ball bearings? What is the width of the roller from center of wheel to center of wheel (for track size)?
What is the weight bearing limit?

The 23-136 is a standard hanger for doors up to 125 lbs. The wheels are not ball bearing. The width of the center of the wheel to the center of the wheel is 1-7/32", take a look at the included image.

OK, thanks so far. Now, my track is shaped like two 'J's, one 'J' is backward so the curly ends are facing each other. The wheels fit into the curly ends. However, the brass housing has to fit in between the curled up ends. If you can follow that, I need the width of the brass housing just above the height adjustment nut. This will tell me if the housing will fit between the two 'J' tracks. It looks like I have 3/8" to 1/2' clearance.

The housing of the 23-136 tricycle hanger is 1/2" thick. Let me know if you need any other dimensions.
