The invention relates to a radial ball joint (1, 50, 70) for a vehicle. The radial ball joint (1, 50, 70) has a housing (2, 51) for receiving a joint ball (11) of a ball pin (6) in a rotatable and pivotal manner. An upper bearing shell (7), which has a contact region (21) that rests against the joint ball (11) and which is made of steel sheet, is arranged between an inner wall (10) of the housing(2, 51) and the joint ball (11) in order to circumferentially support the joint ball (11) in a sliding manner between the equator (12) and the upper pole (13) of the joint ball. According to the invention, the upper bearing shell (7) is designed as an annular, circumferentially closed drawn part and has multiple lubrication grooves (14) in the contact region (21) resting against the joint ball (11), said lubrication grooves passing through a wall (20) of the upper bearing shell (7) in the form of an embossment. 本发明涉及种用于车辆的径向球窝接头(1、50、70)，其中，所述径向球窝接头(1、50、70)具有用于可旋转和摆动运动地容纳球销(6)的接头球体(11)的罩壳(2、51)。在罩壳(2、51)的内壁(10)和接头球体(
