what depth 5x11 bearings for 36mm afterburner v2 motors?

Ok i have heard a lot about the bearings going in some setups in these motors im about to order some parts and im wondering if anyone knows what depth bearings these are.

I suspect these are 5x11x5 bearings like the feigao 540 motors but i wonder if anyone has taken them apart and measured them.

I really like this 3300kv v2 50mm motor and it works very nicely with my mamba max in my losi xxxt on 3slipo.
