Abstract
A ball cage for a constant velocity plunging joint which having an outer joint part with a internally cylindrical guiding face and an inner joint part with an outer spherical guiding face and torque transmitting balls held in the ball cage. The ball cage includes a plurality of circumferentially distributed windows (3) for receiving the torque transmitting balls, and defining a central window plane (M); an outer free face (10) and an outer spherical control face (9) for guiding the ball cage relative to the outer joint part; and an inner spherical control face (16) for guiding the ball cage relative to the inner joint part. The center of the outer spherical control face (9) and the center of the inner spherical control face (16) are positioned at an axial distance from the central window plane (M). The outer spherical (9) is hard-machined and the outer free face (10) is soft-machined.
