Abstract
An assembly for an angular position measuring device includes a shaft having a measuring standard for measuring a rotational movement about an axis. The shaft has a shoulder as an integral component, on which a roller bearing is mounted in axial abutment. Arranged between the shoulder of the shaft and the roller bearing is a groove which is oriented with a radial directional component and is connected to a hollow space for receiving lubricant, the hollow space being bounded in the radial direction by a ring of the roller bearing and by the shaft.
