Abstract

The invention relates to an arrangement for measuring radial forces of a bearing, the arrangement comprising a sensor frame (5) that is mounted adjacent to a bearing case (2) of a device, in a space (4) provided on the side of the action direction of the radial forces (F) of the bearing (3) in the bearing case such that it is exposed to radial forces of the bearing when the device is used; a measuring sensor (6) of radial forces which is attached to the sensor frame and is located in the sensor frame substantially on a plane passing through the radial plane of the bearing (3) or close to it; and means (7) for transferring measuring results provided by the measuring sensor (6) outside the sensor frame, the outer track (9) of the bearing (3) being in immediate contact with the sensor frame.
