Bearing device for a vehicle axle

A bearing device for a vehicle axle, comprising:

• an outer ring having at least one flange at approximately the middle in the axial direction of said outer ring on an outside circumferential surface of the outer ring and with a mounting face facing in a first axial direction and adapted to abut a corresponding mounting face on a support, and a detecting member receiving hole extending radially at approximately the middle in the axial direction at a position circumferentially spaced around said outer ring from said mounting flange;
• an inner ring means having a center opening through which an axle passes;
• a pulser ring mounted at approximately the middle in the axial direction of the inner ring means on an outside circumferential surface of the inner ring means;
• rolling elements positioned between the outer ring and the inner ring means;
• and
• a rotation sensor consituted by a detecting member inserted in the hole in the outer ring and a mounting member orthogonally extending from the detecting member in a direction opposite said first axial direction and secured to the outside surface of said outer ring;
• the face of the mounting member facing in the first axial direction being spaced slightly in said direction opposite said first axial direction from said mounting face of said flange.
