Definition of "babbitt"

Figure 2 represents a top plan of the "Babbitting" jig, placed in or upon a cast-iron frame, preparatory to the pouring or casting of the "Babbitt" or other soft metal on to or around its journals, to form journal bearings in said cast-iron frame.

Remove all sharp edges from the babbitt with a chisel or file and try the shaft after removing the paper wrapping for a fit. If a light coat of oil mixed with lampblack be smeared on the shaft and the shaft revolved, the lampblack will catch on the high points of the babbitt, then by removing the shaft and scraping off these high spots a good bearing can be produced.

Coins made from nickel babbitt are fairly hard and give a clear bright ring. This makes it easier to pass them due to the widespread belief that a sure test of a counterfeit coin is to drop it on a hard surface to see if it will "ring". […] The simplest test is to cut the edge of a suspected coin with a pocket knife. If it is made of babbitt the metal will pare off quite easily.

The cross-head is cast of crucible steel and faced with Babbitt. […] The rod is secured to the crank pin by body bound bolts, this bearing being provided with Babbitt shells which are prevented from turning by paper liners extending to the pin.

Perhaps the most familiar soft bearing alloys are the babbitts. These have been in use since the early 19th century when printer's type metal was utilized for machinery by casting it into holes drilled in iron housings. […] Babbitt or whitemetal bearing materials represent a class of alloys developed specifically for bearing applications.

1992, William A. Glaeser, “Soft Metal Bearing Materials”, in Materials for Tribology (Tribology Series; 20), Amsterdam, London: Elsevier Science Publishers, page 72

In most applications, the inner bearing surface is made of a thin layer of a soft white metal (babbitt), which has a low melting temperature.

Babbitts may be lead-based (as 75%Pb, 15%Sb, 10%Sn) or tin-based (as 89%Pb, 3%Cu). They use lead or tin as a soft matrix metal and hard particles of Sb-Sn or Cu-Sn to resist wear. Because of their softness, babbitts are unrivalled in conformability and embeddability. […] Because of low strength and high cost, a thin babbitt overlay, usually about 0.025 mm, is often deposited as liners over steel bushings to combine the great load carrying capacity of steel with conformability and corrosion resistan[ce] of babbitts.

The caps for these journal-boxes or bearings may be Babbited by this same jig, and they would, of course, exactly conform to the other portions of the bearings in the frame. […] This drilling jig is a negative of the interior of the frame. It has two sets of bearings, c d and e f, which are at right angles to each other, and which set in the longitudinal and transverse bearings that have been made and "Babbited" in the cast frame, and thus steady and hold it.

These bearings, with their caps, are babbitted with metal of the finest quality, a jig representing the shafting being used to locate and regulate the proportion of the bearing precisely.

The work of babbitting bearings offers considerable opportunity for the use of different forms of fixtures that are capable of making a material increase in the efficiency with which this operation can be carried on.

The common way may be described as babbitting one-half of the bearing at a time: then by means of pasteboard liners between the halves, making the other half complete. […] It takes half the time required to babbitt the bearings in halves.

To babbitt any kind of box, first chip out all of the old babbitt and clean the shaft and box thoroughly with benzine. […] In babbitting a solid box cover the shaft with paper, draw it smooth and tight, and fasten the lapped ends with mucilage.

One speaks of a babbitt habit, a babbitt era. Nothing is more true. America recognized itself in Babbitt, it demurred, but it also admired.

[...] a "babbitt" is a person full of self-confident bluster who is nevertheless a narrowminded philistine and a hypocrite.]

Ira relished telling the story that Fred Astaire took him aside and said he knew what a babbitt was, but what was a bromide?
