A device (), for the checking and measurement of the journal bearing clearance between the outer bearing on the rudder shaft () of a rudder for water-borne craft and the inner bearing () on the rudder trunk () corresponding with the outer bearing (), is characterized by a measurement rail () made of a springy elastic material having internal stiffness, which can be introduced by means of a guide rail (), provided with a grip-type handle (), into the gap between the outer bearing and the inner bearing and hence into the clearance measurement region, with a measurement probe () located at its free end () for the clearance width measurement, wherein the measurement rail () with the measurement probe () with a prescribed thickness (a) are exchanged for measurement rails with measurement probes with other thicknesses until the achievement of an agreement of the clearance width with the thickness of a measurement rail () with the measurement probe ().
