Babbitt: The Other Bearing Lubriion

The bearing surface is saced, with Babbitt actually becoming the lubricant, and the shaft surface is preserved in case there is a loss of lubriion or other operating anomaly. In the 17th century, Robert Hooke began utilizing “bell” metal as a bearing surface material. Bells were often formed with a bronze alloy that usually included

Babbitt | Dr. Mel''s Technical Notes

October 11, 2010. A Babbitt bearing bore that has been “scraped” will conform to the shaft journal it supports. A scraped bearing will not create a converging oil wedge which is necessary for proper vibration and temperature control. TRI highly recommends bearings that are machined to tight tolerances.
