Discusses the bearing design for an infrared optical instrument for the Air Force's F-111 reconnaissance fighter and other aircraft. The unit receives infrared radiation from target objects to permit nighttime and adverse-weather target acquisition. The package sits in a pod in the nose, wing or belly of the aircraft. Because image clarity is critical, rotational and focal accuracy of the unit is of paramount importance, even under conditions of severe vibration. The bearings which support the rotating optics package must therefore possess minimal axial and radial runout, maximum rigidity or stiffness, low rotational torque, and be as lightweight as possible for this airborne application.
