if you had a bearing with 55.00mm outer diameter, what size hole would you bore to fit this bearing into ?
edited to add: into a mild steel housing

thanks

depends on the materials into which you plan to mount the bearing,.. but standard values for steel / aluminium etc are available on the bearing manf www's

There are hundreds of fits for bearings/bores. It really depends on the application. What is the purpose of the bearing?

its a lower headstock bearing on a custom bike frame , taper roller bearing 32006.

the frames been built for me, the stock has been bored to 54.6mm, hence the question before i call and complain !!

thanks

54.6 is way too small. You are looking at something like a P5 fit of -0.027 to -0.040

I'll check tomorrow when I have access to my standards library
