Plain Bearings
A plain bearing is a simple mechanism consisting of two sliding components. This lightweight, compact, and inexpensive bearing is widely used in many types of equipment and is sometimes referred to as a Babbitt, bushing, or journal bearing.
Plain bearings are mechanical components charged with bearing a load and allowing a sliding or rotational motion between two parts of a machine. Their main purpose is preventing wear of the points of support of the machine, which would take place if the shafts were to roll directly on the structure.
