Spindle (30) accommodates a cable or wire harness (35) therewithin and is rotatable within the bushing to accommodate twisting of the harness due to displacement of the helicopter blades. An electrical connection to hub (15) is made via flexible conductor (75), the spindle, and flexible conductor (60).
