This paper describes the use of the SHABERTH computer program supplemented with experimental temperature and skid data to quantify steady-state bearing operation. Parametric studies on ball diameter and number, contact angle, curvature, grease type, and preload are presented with their influence on contact stress, fatigue life, skid load, film thickness, and inner and outer race temperatures. These results are compared for a steel versus hybrid bearing set in a DB and DFSL mounting. The method presented can be applied to the design of other steel and hybrid ball thrust bearing systems.
