Abstract
Disclosed is a hub and a bearing which cooperate to hold a shaft in steady axial alignment with a rotor. In a preferred embodiment, the shaft is coupled to the rotor of a fluid gear pump. The gear pump is located in a pump assembly between a front cover and a rear casing. A hub receiving pocket is formed in the front cover, and the hub is connected to the front cover for receipt within the hub receiving pocket. The bearing is surrounded by the hub such that the shaft runs through the bearing to be coupled to the rotor of the gear pump. A pair of high pressure seals are located within the hub at which to surround the shaft and prevent leakage. The bearing being surrounded by the hub stabilizes the shaft to minimize wobbling in response to axial and radial loads to which the shaft is subjected while rotating.
