Abstract: Measurement device (1) for measuring the axial and/or radial load on a bearing (10) comprising an inner ring (11), an outer ring (12) and a plurality of rolling elements (13) between the inner and outer ring. The measurement device (1) comprises a sensor ring (3) which may be positioned adjacent to and in close contact with the inner ring (11) or outer ring (12) of the bearing (10), the sensor ring (3) having at least one weakening (2) at its circumference and at least one sensor (5) being positioned in the at least one weakening (2).

Abstract: A bearing is provided including a first part provided with a first coil (4) and a second part rotatable with respect to the first part about a bearing axis and being provided with a second coil which is electromagnetically coupled to the first coil. The first and second coil are magnetically enclosed by a first covering and a second covering, respectively. The first covering is fixed to the first part and the second covering is fixed to the second part. An air gap is formed between facing ends of the first and second coverings, with at least one of the facing ends of the first and second coverings being provided with at least one recession, such that the air gap varies when the first part and second part rotate with respect to each other. This may be used to provide an indication of speed (bearing rotation) without further sensors.
