Journal Bearing and Its Classifiion | Mechanical Engineering

The portion of the shaft which is in actual contact with the bearing is known as journal. For every machine and engine, it is necessary to have a provision for the support of rotating shaft. Such support is called bearing. In other words, the shaft must be supported through bearing. Simple bearing has been shown in Figs. 8.11 (a) and 8.11 (b).
