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.
