Auxiliary bearing landing tests have been conducted on a 6 MW vertical motor compressor. The corrosion resistant auxiliary bearing system for the motor compressor is a unique combination design with one auxiliary bearing of bushing type design and the other, a rolling element type design. The results of the landing test were good, with 5 landings completed and with the auxiliary bearings fit for further service. Corrosion resistant auxiliary bearing designs are described. Analysis methods and design considerations for auxiliary bearing systems are discussed.
