A method for measurement of axial forces acting on a shaft (10), the faces of a portion (12) projecting from said shaft (10) being supplied with gas under overpressure such that gas pressure is built up between two opposing faces (16; 17) of said portion (12) projecting radially from the shaft (10) and at least one gas-permeable body (15) provided external to said faces (16; 17). A gas differential between the gas pressure on said opposing faces (16; 17) is established, and the axial force acting on said shaft is determined as k* DELTA P, with k being a constant and DELTA P being the pressure differential between the gas pressures on the two faces (16; 17). Means are provided for supply of gas under overpressure to said body (15), and pressure measuring means (18) are provided for measurement of the pressure differential between the pressures on the two faces (16; 17) of the radially projecting portion (12). The protruding portion (12) may also constitute a measuring plate which, provided in various manners, is subjected to forces.
