This class is the generic class for devices, known as bearings,
designed for general use, where one element continuously bears the
weight of another, either suspended therefrom, or imposed thereon,
and wherein there is either linear motion (e.g., a cross head) rotary motion
(e.g., of a shaft or axle), or oscillating movement, (e.g., a lever)
between the two elements. The bearings may have either sliding,
or rolling contact with the supported member.
The class includes (a) supports for bearings where such supports
are specially formed to receive, and are placed in combination with,
bearings, and when not limited to any classified art; (b) antifriction
means, as balls, or rollers, designed to receive a rotating shaft,
or to be used in connection with a pivoted, sliding, or rotary element; and
(c) lubricating devices wherein any of the above bearings are modified
for receiving and supplying lubricant.
This class including methods pertaining to bearings, when
not otherwise provided for.

Note. Patents issued prior to 1950 have not in all instances
been classified by their claimed disclosure so that placement of these
older patents does not necessarily indicate lines of classification.

Note. Necessary but not particularly sufficient criteria
for inclusion in this class are that the "bearing" (1) have at least
two moving parts that slide or roll against one another and (2)
should be intended to reduce friction between significantly more massive

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Where the bearing forms but an element of a structure, and

see the appropriate art class.

in the claims to limit the product to bearing use, it is classified
elsewhere.
