Abstract:
An integrated shaft bearing assembly is provided having a housing with at least one bearing located in the housing that supports a shaft that extends through the housing. A vent ring is located at one axial end of the housing, with the vent ring having a radial flange that extends toward the shaft. A face seal assembly including a seal support ring is fixed on the shaft. The face seal assembly includes a bellows spring connected to the seal support ring, a face seal carrier connected to the bellows spring, with the face seal carrier supporting a face seal against the face of the radial flange. Here the vent ring is integrated with the integrated shaft bearing and provides a surface for the mechanical seal as well as venting to avoid pressure build up in a region of the mechanical seal between the mechanical seal and the bearing.
