A force-transducer system for measuring a force under shearing, wherein the force acts from the outside in a radial direction transversally on a longitudinal axis of the force-transducer system, comprising: a cylindrical pin body radially positioned internally; and a hollow-cylindrical sleeve body radially positioned externally, which extends coaxially to the longitudinal axis and is configured to coaxially receive the pin body, wherein the sleeve body comprises: at least one first section for supporting the force-transducer system, which first section is positioned externally in an axial direction and arranged at a front end; at least one second section for measuring the force; and at least one third section for radially introducing the force into the force-transducer system; wherein the pin body is positioned in a form-closed manner in the first section, and wherein a surface of the pin body comprises a circumferential surface being orientated in a circumferential direction, and two front faces axially arranged oppositely; wherein the second section comprises a radial outer and/or inner groove running circumferentially so that respectively one step (28-1, 28-3; 28-2, 28-4) is formed in the axial direction between the first section and the second section as well as between the second section and the third section, and wherein the second section is configured to radially receive at least one measuring cell; wherein the third section comprises an axial length, a radial outer outside wall, and a radial inner inside wall, and wherein the third section, in an unloaded state in which the force does not act, is spaced radially along its entire axial length to the pin body so that the pin body is positioned in a contactless manner within the third section, wherein the second section, the third section, and the pin body define between each other a deformation space arranged radially and axially within the force-transducer system, into which the sleeve body can dodge in a loaded state in which the force acts on the force-transducer system, for deforming the second section under shearing; characterized in that the inside wall of the third section - or a region of the circumferential surface of the pin body positioned radially oppositely to the inside wall of the third section - comprises at least one projection projecting radially into the deformation space so that the insinde wall of the third section gets in contact with the circumferential surface of the pin body via the projection, if the force reaches an over-load threshold value. a cylindrical pin body radially positioned internally;
