I know, they have specifications and parts that are specific to a certain airplane, but is the actual wheel the same old two piece wheels. For the sake of manufacturing, most manufacturers try to minimize overhead cost by making a single part multi adaptable.
Here's what I do know. (and that's usually very little, just ask my better half
I also know that there is a 1 1/4" axle and a 1 1/2" axle version. I originally thought that these two axle sized wheels just used a larger bearing race to size the axle hole down to 1 1/4", but I measured a wheel on a Supercub, which are 1 1/4" and the inner casting where the bearing resides are different, at least the ones I measured were.
