The inner ring of a rolling bearing is mounted on one end of a rotary shaft where the shaft is of reduced diameter. The inner ring of the bearing bears on the larger diameter part of the shaft but projects beyond this part to define an annular space with the reduced diameter part of the shaft. A circular-sectioned ring of elastomeric material is located in this annular space. This ring is pressed into the annular space by a washer of smaller diameter than the internal diameter of the bearing, which is mounted on the end of the shaft and is locked against the ring by screw means engaging the end of the shaft.
