The Art of Bearing Babbitt Selection
While not subject to precise calculations, the following considerations must also be taken into account:
- Continuity of service
- Bonding characteristics
- Cooling facilities
- Lubrication
- Cleanliness
- Maintenance schedule for the bearing in use
- For example, a bearing in continuous use in a harsh environment without regular maintenance will require different Babbitt and lubrication than a bearing in intermittent use in a clean, light duty environment. This so-called art is really the condensation of the experience of the technician and the experience of the bearing being rebuilt.
If the bearing has performed well in use over many years, the bearing needs simply to be rebuilt to its original specification and formulation. In this case the technician’s greatest concerns are:
- Bearing shell surface preparation
- Bonding characteristics of the tinning compound and the Babbitt layer and,
- Load bearing surface preparation and finish

Famous quotes containing the words the art, art, bearing and/or selection:
“The two great things yet to be discovered are these—The Art of rejuvenating old age in men, & oldageifying youth in books.—Who in the name of the trunk-makers would think of reading Old Burton were his book published for the first to day.”
—Herman Melville (1819–1891)
“The art of pleasing is the art of deceiving.”
—Luc, Marquis de Vauvenargues (1715–1747)
“New York, home of the vivisectors of the mind, and of the mentally vivisected still to be reassembled, of those who live intact, habitually wondering about their states of sanity, and home of those whose minds have been dead, bearing the scars of resurrection.”
—Muriel Spark (b. 1918)
“Judge Ginsburg’s selection should be a model—chosen on merit and not ideology, despite some naysaying, with little advance publicity. Her treatment could begin to overturn a terrible precedent: that is, that the most terrifying sentence among the accomplished in America has become, “Honey—the White House is on the phone.””
—Anna Quindlen (b. 1952)
