If lasting high loads are applied to hip joint prostheses, signs of wear occur even if hard materials are used. While these signs do not result in failure, for example in the breakage of a component in prostheses made of ceramic materials, they are still undesirable. The abrasion occurring by friction when using metal-on-metal material pairing can be harmful to the human body. According to the invention, therefore a socket insert of a hip joint prosthesis is proposed, wherein the spherical head of a femur is supported in the spherical recess-shaped clearance of the socket insert, wherein this spherical recess has a break-in zone, which on the one side ends with a circular arc tangentially in the face of the socket insert and on the other side extends up to the break-in edge, and which is characterized in that between the start (12) of the circular arc (7) with the radius (11) of the length (RE) and the break-in edge (5) of the spherical recess (3) with the radius (13) of the length (RK) the break-in zone (6) forms a curve (14), the function of which can always be differentiated twice in every point.
