What size are Campagnolo Ultra Torque bottom bracket bearings? I was unable to find the dimensions of Campagnolo bottom bracket bearings. My understanding is that bearings have standard sizes with names like "6200", "6201", etc. See this chart for a big list. 

Knowing the size would allow me to buy compatible bearings from manufaturers other than Campagnolo, which might offer better performance for the money.

Edit

I am interested in the ITA and BSA threaded variants. If anyone can source the full list then I'm sure others would find that helpful too.

I was able to find an answer on the Wheels Manufacturing Page with a bit of Googling.

Looks like Campy Power and Ultra Torque use a 25mm axle and 6504 size bearings. 

The Ulta Torque crank requires 6504N bearing. I believe the N post-fix means that outer bearing shell has a snap-ring groove into which a retaining clip on the bearing cup fits.
