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 NSK 6304 Bearing shafts were to roll directly on the structure.
