Abstract
Abstract A swivel hinge wherein a pair of cup shaped bearing rings are aligned in the same axial direction and have a plurality of balls arranged therebetween. Each of the bearing rings has an axially outward directed hinge supporting shoulder which is adapted to be received by respective hinge leaves, and a radially outward extending ball race surface supporting the balls. Each of the ball race surfaces terminate in an axially inwardly directed annular flange, the flange of one of the rings overlying and gripping the flange of the other of the rings so as to seal the bearing.
