摘要：A roller bearing arrangement (1) with an angle sensor (3) comprises a rollerbearing (2) with which an angle sensor (3) which operates according to the principle ofvariable reluctance, which is embodied as an absolute value signal transmitter and whichhas a sensor ring (9) which is connected in a rotationally fixed fashion to one of thebearing rings (4, 5) of the roller bearing (2) and a measuring scale (10) which is connectedin a rotationally fixed fashion to the second bearing ring (5, 4) and is embodied as a ring,wherein coils (21, 22, 23), specifically at least one transmission coil (21) and at least onereception coil (22, 23), are arranged on the sensor ring (9), and the transmission coil (21)has an axis of symmetry which is identical to the rotational axis (R) and is arranged in anannular metallic pot core (11) which has a U-shaped cross section and is concentric withrespect to the rotational axis (R) of the roller bearing (2), and a reception coil (22, 23) isarranged partially inside and partially outside the pot core (11).
