How to get the axle out??

[Nvreloader]

Hey guys
This is a drawing of my rear hub, I need to get the axle out for measurements, so I can get the correct Robert axle for my trailer installment, the OEM axle is a QR type 190mm in length.
I am attempting to figure out HOW.??????
Any suggestions would be greatly appreciated,
Tia

does it have the usual quick release or a through axle? Kinda looks like a through axle so thats usually 12mm or 15mm. a pic would help.

Here is a photo of the rear hub, (Top Hub) 5mm QR type 190mm in length. I have not found any threads, hidden keys, set screws etc, used for removal for the center axle.

I don’t understand why you would need the inner axel length but…

The end caps are pressed on, not hard to get off but easily damaged without the correct tool.

the free hub likely unscrews once the cap is out. ( some just slip off with the cap)

if you have a depth gauge the inner axel length can then be worked out, otherwise start driving bearings out.
