| Captain_Dingo:
I can tell you that the inside diameter of my bearings is 5mm, from comparing them to a router bit bearing. I forget what the outside diameter is. I'd email Bob Roberts and see if he knows the exact specs. I don't have any calipers here that I can use to get you an exact measurement, unfortunately. |

I just ordered some bearings from McMaster Carr (www.mcmaster.com). They stock 1 each, everything in the world of hardware. I'll have to remeasure them though. If I haven't posted numbers by tomorrow, pm me to remind me. |
