Even for large ships, the cast bronze bearings used in rudder carriers are designed for loads below 10 kg/sq cm, and the development of small bearings capable of withstanding comparatively large loads has become important. The Authors describe experimental investigations on this problem. Tests were made on the frictional properties and wear resistance of several possible materials for sliding surfaces, including cast metals, self-lubricating metals, and plastics; the effects of oil-groove design were also taken into account. The results of these tests are presented. The most promising combination was cast-steel and plastics, with suitable oil-grooves, and a new rudder-carrier bearing based on this result was manufactured. The bearing, which has a loading capacity of between 20 and 40 kg/sq cm, was fitted in a 150,000-dwt ship; no trouble occurred during six months' service, and the bearing was then inspected and found to be undamaged.
