Abstract
A device for sealing and generating electrical pulses in a bearing assembly including fixed and rotating bearing rings especially a wheel bearing for motor vehicles. The device consists of a sealing section on the fixed bearing ring with an embedded pulse generator for detecting rotational movement and a sealing section on the rotating bearing ring having cells a certain distance apart from each other which activate the pulse generator. The fixed bearing ring (4, 19) rotates with respect to the sealing section (2) which is secured against rotation by way of a machine element (1, 24), which holds the fixed bearing ring (4, 19).
