Precision balance including a weighing dish supported by a support member which is guided by means of guide arms in such a way that weighing dish performs essentially a vertical movement during weighing. The spacing between the ends of the guide arms is effected by means of a differential screw which changes the width of a slot formed in the frame of the balance. A V-shaped insert is placed in the slot. The insert has linear contact with the sides of the slot. When the portion of the frame located above the slot is being bent by the differential screw, an exactly defined bending line is ensured.
