Looking at the original specs of the centrifuge, I wonder whether it is possible to bring a centrifuge up in parts and have it assembled somewhere within the ISS.
These are the CAM Centrifuge Rotor (CR) specs:
The CR is the largest (2.5m diameter) equipment for gravitational experiments. It provides a selectable, simulated gravity environment from 0.01g up to 2.00g (0.01g increments) for biological specimens on ISS. Small animals and plants could also be used in experiments with the CR, and significant advances for those gravitational experiments are expected.

I do not think it would be a problem to bring up a similar centrifuge rotor in parts and assemble it on orbit by the crew. However, where could it be located + what about the vibration environment, power requirements etc.? The only viable location I can think of is the back-side of the PMM.
