The invention relates to a bearing, preferably for a shaft lever in a weaving machine, having an inner bearing ring (1) and an outer bearing (4), which execute a limited rotating movement in relation to each other. The interior of the bearing is sealed by two sealing rings (10) fitted on the face of the bearing. Durable and resistant sealing of the bearing is achieved in that both sealing rings (10) are connected to the outer bearing ring (4) via a rigid outer retaining ring (12). The sealing ring (10) stretches radially inwards from this outer retaining ring (12), in the form of a membrane, and ends in a bulge (11). The sealing ring (10) is fixed in a cavity (8) in the inner bearing (1) by means of this bulge (11).
