The invention refers to a flanged ball pin to be utilized in steering and suspension systems of automotive vehicles, and a method for manufacturing thereof. The ball pin includes two separate pieces: a single-piece ball rod having a spherical ball portion and a cylindrical shank member, and an annular flange member secured over the shank member. The method for manufacturing the ball pin is preformed in the following manner: first, the single-piece ball rod is formed, and the annular flange member is manufactured, so that diameter of the shank member and a diameter of an opening in the flange member are dimensioned for an interference fit. Then, the flange member is mounted over the shank member and slid along the shank member until the flange member engages a stop flange on the shank member and is secured about the shank member by interference fit.
A sealed spherical bearing having a bearing housing (1), a ball (2) located therein and a ring-like seal (4) having an inner edge (6) and an outer edge (5) located between the bearing housing (1) and the ball (2), one of the edges (5, 6) having a head (7) and a skirt (12) depending therefrom, the head (7) lying in an annular groove (8) formed in one of the ball (2) or the housing (1) and the skirt (12) lying on a lip (9) upstanding from the groove (8) to define at least two sealing lines between the seal (4) and the one of the ball (2) or the housing (1), the other edge of the seal being fixedly mounted to the other of the ball (2) or the housing (1).
