ABSTRACT:
A conical bearing system includes a first conical bearing having an integral shaft and a second conical bearing defining a bore having a shaft mating bore section and a threaded bore section. The system is assembled by applying adhesive to the shaft and inserting the shaft into the shaft mating bore section. A threaded screw is then screwed into the threaded bore section until the screw abuts the shaft. Then torque is applied to the screw to push against the shaft thereby causing the second conical bearing to move axially. Once the adhesive has cured, the screw may optionally be removed.
