Abstract
The disclosure provides an improved shaft design. The design includes an elongated annular shaft body, having an outer surface and defining a hollow cavity, and a core insert disposed in the hollow cavity. The shaft body has one or more radial flow ports that align with at least one fluid conduit in the insert. A pin couples the insert to the shaft body to prevent rotation of the insert relative to the shaft body. The shaft and the insert can be of different materials, for example, such that the density of the insert is less than that of the shaft body.
