What is Babbitt, bearing pad why plating Babbitt.
In the face of Babbitt opened the examination revealed a large area of black, is this because of lubricating oil, or Babbitt materials in long-term operation will appear after the table black, the lubricating oil pressure of 2.5 kg, the temperature is 45-49 degrees. Oil No. 68.
Babbitt is the most widely known bearing material, and its application dates back to the industrial revolution. Babbitt is only suitable for relative to the low hardness of shaft material, compared with other bearing material, has better adaptability and swaging, widely used in large marine diesel engine, turbine, generator, and other large rotating machinery. Babbitt alloys can be simply divided into three types: high tin alloys, high lead alloys and intermediate alloys (both tin and lead in alloys are very important). In all these alloys, both antimony and copper are important alloying elements and hardening elements, and the structures are composed of hard intermetallic compounds dispersed in the soft matrix
