I need to get some new hubs machined and i just need to finalise the ID of the hub.

My wheel bearing OD is 72mm exactly. So what ID should my hub have?

Thanks

72 mm, but tell the machinist you need an interference fit, and he will machine a couple of thou undersize accordingly.

I would give them the bearing to work from.

Ok many thanks guys
