Wheel-support bearing unit

Wheel bearing unit (1) comprises rolling bodies (11) arranged between an outer part (8) and an inner part (10). The ratio of the diameter of a partial circle of a row of wheel bearing units to the diameter of the rolling bodies of each row is more than six. The partial circle has an imaginary circle which is concentric to the axis of rotation of the wheel bearing unit to connect the centers of the rolling bodies of one row. Preferred Features: The distance between the rows corresponds to the 1.22 times the diameter of the rolling bodies. The distance of the rows is the axial distance between the centers of the rolling bodies.
