Babbitt, also called Babbitt metal or bearing metal, is any of several alloys used for the bearing surface in a plain bearing.The original Babbitt metal was invented in 1839 by Isaac Babbitt in Taunton, Massachusetts, USA.He disclosed one of his alloy recipes but kept others as trade secrets.n the traditional style of a babbitt metal bearing, a cast iron pillow block is assembled as a loose fit around the shaft, with the shaft in approximately its final position. The inner face of the cast iron pillow block is often drilled to form a key to locate the bearing metal as it is cast into place.
Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts. The term bearing is derived from the verb  to bear ; a bearing being a machine element that allows one part to bear (i.e., to support) another.ome applications apply bearing loads from varying directions and accept only limited play or slop as the applied load changes. One source of motion is gaps or play in the bearing. For example, a 10 mm shaft in a 12 mm hole has 2 mm play.
