A self-closing door hinge which may be mounted for clockwise or counterclockwise opening of a door. Hinge arms are provided which permit the hinge socket part and hinge axle to be uprightly oriented irrespective of the orientation of the hinge leaves to which they are fixed. The socket part includes an inner socket having a pair of vertically spaced, inclined, orbital rail grooves. The axle has recesses which hold ball bearings which support the socket part and ride in the grooves so that the door automatically closes when the door is released with the ball bearing on the inclined portion of the orbital grooves.
