A braking arrangement for braking a shaft, in particular rotor shaft of an electric motor, wherein the braking arrangement has an armature disc which is connected, non-rotatably but axially movably, to a magnet body of the braking arrangement, wherein the braking arrangement has a roller carrier and a cam disc, wherein rollers which can be rolled on control faces of the cam disc are rotatably mounted on the roller carrier, wherein a limiting part which is supported on the roller carrier on that side of the roller carrier which faces away from the armature disc, and is supported by way of a first sliding ring functions as an axial limitation of the armature disc, can be supported on that side of the armature disc which faces away from the roller carrier and/or magnet body, in particular can be supported by way of a second sliding ring, wherein the cam disc is arranged between the roller carrier and the magnet body, characterised in that the limiting part, screw or grub screw - has a first widened portion, nut screwed on the screw head or onto a threaded region of the limiting part, the first widened portion being able to be supported on the armature disc on that side of the armature disc which faces away from the magnet body, and - has a second widened portion, nut screwed on the screw head or onto a threaded region of the limiting part, the second widened portion being able to be supported on the roller carrier on that side of the roller carrier which faces away from the magnet body. wherein the braking arrangement has an armature disc which is connected, non-rotatably but axially movably, to a magnet body of the braking arrangement, wherein the braking arrangement has a roller carrier and a cam disc, wherein rollers which can be rolled on control faces of the cam disc are rotatably mounted on the roller carrier, wherein a limiting part which is supported on the roller carrier on that side of the roller carrier which faces away from the armature disc, and is supported by way of a first sliding ring functions as an axial limitation of the armature disc, can be supported on that side of the armature disc which faces away from the roller carrier and/or magnet body, in particular can be supported by way of a second sliding ring, wherein the cam disc is arranged between the roller carrier and the magnet body, characterised in that the limiting part, screw or grub screw - has a first widened portion, nut screwed on the screw head or onto a threaded region of the limiting part, the first widened portion being able to be supported on the armature disc on that side of the armature disc which faces away from the magnet body, and - has a second widened portion, nut screwed on the screw head or onto a threaded region of the limiting part, the second widened portion being able to be supported on the roller carrier on that side of the roller carrier which faces away from the magnet body. - has a first widened portion, nut screwed on the screw head or onto a threaded region of the limiting part, the first widened portion being able to be supported on the armature disc on that side of the armature disc which faces away from the magnet body, and - has a second widened portion, nut screwed on the screw head or onto a threaded region of the limiting part, the second widened portion being able to be supported on the roller carrier on that side of the roller carrier which faces away from the magnet body.
