Identify axle??

[Mi racer 22]

What do you measure to find out what axle you have? OD on mine measures 1.5in but i dont find any axles that size so I'm betting its metric. Need help on finding out what I got.

1-1/4 is standard for most oval karts, the sprint karts come in metric sizes 30, 40, 50 millimeters.

That looks like 40mm to me if it's 1.5. Actually if it's a tad over 1.5 inches then it's 40mm.

Yeah it looks like it's a 16th over 1.5in. what would measurements be for other two sizes? I need to order new bearings for axle and want to make sure I order correct size

40mm = 1.575"
50mm = 1.969"
30mm = 1.181"
1mm = .03937"
