What are cylindrical constraints and could they help me?

Hello, about 2 weeks ago I asked a question about using a thrust or tween to go in a exact circle. Now, I have something that could help me: a cylindrical constraint. I heard it would limit anything attached to have boundaries which would be shaped like an exact circle. Any help would be appreciated. For context, (and because an admin said I need more information lol), I'm making a part which will spin around in a circle, and be able to be rotated as if a hinge constraint was below it.
