Are there dimensional changes with anodizing?

Reason I'm curious, I made this hub for a customer right before I left to go hunting. It's a prototype for an electric bike, so stronger than bike hubs, but compatible with bike disc brakes and chain rings etc. The recesses on the ends are bearing press fits. As I'm leaving he mentioned he was so happy with it he was going to have it anodized... I didn't have time to look into if the anodizing would change the ID's of those pockets.
