What is a Journal Bearing?

These are also known as Sliding Bearing. It consists of a journal that rotates inside a bearing. Here journal refers to the shaft. The part of the shaft which rotates inside the bearing is known as the journal. It is very simple in construction with no rolling surfaces. The journal slides over the bearing surface and therefore it is also known as Plain bearing for being very simple construction-wise.
Type of Journal Bearings-
1. Hydrodynamic Lubrication
2. Hydrostatic Lubrication
3. Thin Film Lubrication
4. Dry Lubrication / No film Lubrication

Plain Bearing Uses

Journal or Plain bearings are the most widely used types of Hydrodynamic Bearings. They are used in:
- Supporting a rotating shaft.
- Supporting crankshaft.
- Supporting Camshafts.
- Used in rocker shaft of rocker arm valve train systems.
