Abstract
A bearing ring, in particular of a rolling bearing or a sliding bearing, including a body made of a magnetostrictive material, having a first raceway () and a second, axially spaced apart, raceway () and a permanent magnetization () which is impressed into the material of the body between the raceways () and which runs around an axis of rotation () of the body. According to the invention, the bearing ring achieves the object of improving the structural integration of a torque sensor into a bearing, which torque sensor generates a torque-dependent magnetic field by utilizing the inverse magnetostrictive effect.
