Abstract: A constant velocity joint support bearing system having a bearing assembly supporting a first shaft connected to one member of the constant velocity joint. A first labyrinth seal on one axial side of the bearing assembly is formed by a shoulder that is unitary with the outer member of the constant velocity joint and by a radially inward projection on a bearing support bracket holding in place the outer race of the bearing assembly. A second labyrinth seal is formed between a cylindrical section of the bearing support bracket and an annular member that axially retains the bearing on the first shaft. Both the bearing support bracket and the annular member are formed from stamped sheet metal. The shoulder and the annular member are shaped to promote centrifugal slinging of contaminants away from the bearing assembly.
