Zusammenfassung:	A one-piece shaft seal apparatus and related method are disclosed for use in machines having a rotating shaft and a rolling-element bearing. The integral shaft seal apparatus can include a substantially rigid, annular frame secured between a machine support structure and a rolling-element bearing surrounding a rotatable shaft, and some combination of a bearing seal portion extending from the frame, a housing seal portion that can be secured between the rolling-element bearing and the machine support structure, and a shaft seal portion extending between the frame and the shaft, wherein fluid in the race can be separated from fluid sealed by the shaft seal portion. The bearing seal portion can snap in place between the races of the bearing, while the shaft seal portion can be at least partially in fluid-tight contact with the shaft.
