RECENT EXPERIENCE AND DEVELOPMENTS IN BEARINGS FOR DIESEL ENGINES

The paper explores examples of various types of bearing damage, including cavitation erosion, and fretting and indicates how the design has been improved to meet the needs of today's engines. The most significant development in bearing materials has been the increased use of aluminum alloys, principally due to their corrosion resistance. To the 20% tin aluminum alloy widely used in automotive engines has been added 40% tin aluminum for better seizure resistance, particularly in the marine diesel crosshead bearing. High conformability can be obtained by omission of the 1% copper content commonly used in other tin aluminum alloys. For high speed turbocharged diesel engines where formerly only lead bronze had sufficient fatigue strength to carry the big end bearing loads, aluminum 11% silicon is now proving to have a particularly good combination of strength and compatibility.
