Paper Abstract

The extensive review by Shepherd (1991) of bearings for rotary scanners is summarized. Consideration is given to bearing choice, spin axis error, speed, cost, power, life, contamination, vibration and shock, and atmosphere. Alternative bearing types are examined. It is shown that the bearing selection process is an integral part of the scanner design process. The choice of bearings has a dramatic effect on the cost and performance of the scanner.
