DEFINITION

Classification: 384/276

Specified sleeve or liner:

(under subclass 129) Subject matter wherein one of the bearing contact surfaces is defined by an annular member having substantially cylindrical inner and outer surfaces, the thickness between said inner and outer surfaces being less than the radius of said inner surface.

(1) Note. This subclass does not include patents which claim a bearing element solely by setting forth the material of which it is made, of which see the appropriate composition, or stock material classes. In this connection the following classes should be considered.

16, Miscellaneous Hardware,

2.1+, for similar bushings which line openings, or sockets to reinforce the same and/or provide a smooth surface to prevent abrasion of elements passing therethrough or there into, without constituting a bearing.

29, Metal Working,

898+, for methods of making bearings.

75, Specialized Metallurgical Processes, Compositions for Use Therein, Consolidated Metal Powder Compositions, and Loose Metal Particulate Mixtures, for articles defined solely by their metal, or alloy composition. 138, Pipes and Tubular Conduits, for hollow, or tubular stock.

148, Metal Treatment, particularly

400,.

156, Adhesive Bonding and Miscellaneous Chemical Manufacture, appropriate subclass for methods of making a machine element, or bearing by a laminating operation.

252, Compositions,

9+, for lubricating compositions and especially subclasses 12+ for bearings having a lubricating function claimed solely in terms of their compositions.

295, Railway Wheels and Axles,

35, for bushings for railway car wheels.

384, Bearings,

53+, for journal brasses and subclass 216 for antifriction bearings.

415, Rotary Kinetic Fluid Motors or Pumps, 170.1+, and 230+ for a motor, or pump bearing, seal, or liner and including pump, or fluid motor structure of the type there classifiable.

428, Stock Material or Miscellaneous Articles, appropriate subclasses, for a stock material product in the form of a single, or plural layer web, or sheet not elsewhere classified.
