A system for suspending a ceiling fan is provided which allows the ceiling fan to pivot, to accommodate vaulted or sloped ceilings, while preventing the ceiling fan from rotating about a longitudinal centerline axis of the fan. The system includes a hollow canopy defining an interior space and having an upper end portion, which is operatively attachable to a support structure such as the ceiling. The canopy further includes a lower end portion and a central, body portion extending between the upper and lower end portions. The canopy includes a seat which is connected to and extends upwardly from the lower end portion, and a guide which is also connected to the lower end portion and extends upwardly therefrom. The guide has an inner surface which forms a portion of the inner surface of the seat and defines a receptacle which extends through the seat and a bottom surface of the canopy. The seat defines an aperture which also extends through the bottom surface of the canopy. A ball is pivotally engaged with the canopy seat and is connected to a stationary portion of the ceiling fan. A pin is attached to the ball and protrudes radially outwardly from the outer surface of the ball, with the pin being engaged in the receptacle of the canopy guide. The pin has a longitudinal centerline axis which extends through a center of the outer surface of the ball and is substantially perpendicular to the longitudinal centerline axis of the ceiling fan. The ball and ceiling fan pivot about the centerline axis of the pin. The system may also include a hollow sleeve connected to the stationary portion of the ceiling fan, such as an upper end portion of a downrod of the ceiling fan. In this instance, the ball is disposed in surrounding relationship with the hollow sleeve and frictionally engages the sleeve.
