Description: Babbitt Bearing Techniques: Machinery’s Industrial Secrets, originally published in Machinery magazine in the early 1900s, compiled by Lindsay Publications, published by Lindsay Publications, 2000. 5½ x 8½ paperback, 48 pages. ISBN 1-55918-244-X. These days we use bronze bushings, ball bearings, and roller bearings. At one time, though, bearings were cast from Babbitt metal, an alloy of tin, antimony and lead. It was very similar to type metal used in Linotype machines or solder. It was also called soft metal or white metal. Modern knuckleheads laugh at Babbitt. It "couldn't possibly" be any good because it is so soft. "Only modern bearings" are any good. Bull! It was excellent bearing material, but the main reason we don't use it these days is because modern bearings can be much smaller to carry a given load, need essentially no maintenance, and they're now mass-produced making them cheap. A hundred years ago, Babbitt was king. Many people are not familiar with the technique. For instance you might have a cast iron shell for a pillow block. You place the drive shaft through the shell and center it with a simple jig. You melt Babbitt with a torch (propane will do) and pour it into the space between the shaft and the shell. In a couple of minutes the metal has frozen, and you can remove the shaft and check the result. To use your homemade pillow block just put the shaft back into the bearing being sure to supply adequate lubrication. It will run and run and run. It's cheap, fast, and inexpensive. And it performs. Some of the finest lathes ever made had Babbitt headstock bearings. These articles are full of drawings, how-to, arguments among machinists, experiments, discoveries, and experience. Babbitting is something to learn about and use. Afterall, most early 1900's engines - marine, airplane, steam, automobile - used Babbitt in their bearings for good reason. These articles from early issues of Machinery Magazine reveal discussions among WW I era machinists about their techniques, secrets, and discoveries.
