Required torque to move a carousal!

Ok, so I'm doing an engineering project for a carousal and need to spec a motor, therefor I need to know how much torque I need to turn the center shaft of the carousal at 10rpm. If the bearing is considered frictionless how do I find the answer.

Lets say the carousal weights 300lbs, with an additional 60lbs on each side (weight of the rider) at 1.5ft from the center.

The center shaft is 6in in diameter if that matters.

Hmm if the carousel is actually frictionless then why do you need any torque at all to keep it going at 10 rpm?

Once you get it going, you should need approximately 0 torque.

Well you see, my problem is, technically it's not frictionless, but there's no friction factor listed for any bearing in the catalog, so I figured maybe there was something else to it, guess not.
