Abstract
The present invention relates to a bearing assembly that provides a magnetic sensor; a shaft; and a bearing. One of the shaft and the bearing is provided with a surface having a bearing steel and including a magnetic pattern disposed thereon for indicating a rotation of the shaft relative to the bearing. The magnetic pattern is provided by the microstructure of the surface; and the sensor is arranged to sense the pattern and output a signal indicative of a rotation of the shaft relative to the bearing.
