If I read this right a 308 should be 0.906" thick, 3.544" OD, 1.575" bore.
this is what I am finding and it's standard numbers for a 308 bearing , but as snoopy states Timken shows it being narrower which I think is the problem which ebooger ... i think ... stated years ago in an article on rebuilding 833's .
also I think some have a different snap ring groove width .
