The plain journal bearing, shown in Figure 1, is the most basic hydrodynamic journal bearing. As the name implies, this bearing has a plain cylindrical bore. A shaft rotating in a plain journal bearing is illustrated in Figure 2. The eccentric rotating shaft will develop an oil film pressure profile, as shown in the figure.

The journal is supported by, and rotates in, a main bearing. It serves as the center of rotation of the crankshaft. It is surface-hardened to reduce wear. The crankpin is the section to which the connecting rod is attached. It is off-center from the main journals and is often called the throw. Two crank cheeks and a crankpin make a throw.

A journal bearing allows the shaft to rotate while holding it in a fixed horizontal position. On the other hand, a thrust bearing prevents the shaft movement along its length while it rotates. While Talking about journal bearing, on rotation, it creates high pressure in the oil film which supports the journal which is again analogous to the load.
