Insert

 

the part of a sliding bearing that directly supports the journal of a rotating shaft or axle. An ordinary split bearing has two inserts, which are the halves of a hollow cylinder. Less frequently, three or more inserts are made in a bearing.

The material of the insert that comes in contact with the shaft’s journal should have a low coefficient of friction, good run-in qualities, and low wear of both itself and the journal. These requirements are met by antifriction alloys—special metal-ceramic and nonmetallic materials such as textolite, cured rubber, and wood. Thin-walled inserts stamped out of steel strip 1.5-2.5 mm thick and covered on one side with a thin layer of antifriction alloy are commonly used in internal-combustion engines of transportation vehicles. Such inserts, in addition to using a small amount of expensive material, are reliable and considerably simplify machine repair.
