A compressor swash plate includes a base member having a flat plate shape, and a coating layer formed on a surface of the base member and having projections formed in a linear shape, in which the following inequalities are satisfied when a plane part formed on a prism is pressed against the coating layer with a pressure of 30 MPa: 0.01B0.06 and 10S40, where B indicates widths (mm) of surfaces of the projections in contact with the plane part, and S indicates a percentage (%) of a total sum of an area Si of the contact surfaces (a gross area of the surfaces of the projections in contact with the plane part) relative to a reference area (an area of a part of the coating layer against which the plane part is pressed).

To provide a conductive member for an electrophotographic machine that is capable of preventing hardening degradation of a surface layer that is caused by an ionic conductive agent contained in a conductive rubber elastic body layer, allowing the surface layer to be improved in durability. A conductive member 10 for an electrophotographic machine includes a conductive rubber elastic body layer 14 containing crosslinked rubber and an ionic conductive agent, and a surface layer 16 provided on an outer periphery of the conductive rubber elastic body layer 14, wherein the surface layer 16 contains a polymer and polyphenol. Examples of the polyphenol include a tannin, gallic acid, ellagic acid, pyrogallol, catechin, and chlorogenic acid.

The element is formed from the winding of a fabric of small thickness ranging between 20 ?m and 150 ?m and mixed with a resin containing fillers. The fabric has the form of strips having a width ranging between 5 mm and 200 mm, with the strips being crossed in several layers.

A sliding engine component may include a sliding surface including a plastics polymer-based composite layer disposed on a substrate. The composite layer may include a matrix of plastics polymer-based material. The plastics polymer-based material may have 0.1 to 20 percent by volume of liquid-filled microcapsules distributed throughout the matrix, and incidental impurities.

A sliding member includes a sliding layer including graphite particles dispersed in a synthetic resin matrix. The graphite particles have a volume ratio of 5% to 50% and are composed of spheroidal particles and flake-like particles, respectively having a graphitization degree K1 and K2. The flake-like particles have a volume ratio of 10 to 40% with respect to a total volume of the graphite particles. The spheroidal particles have a cross-sectional structure with AB planes of a graphite crystal laminated from a surface toward a center. The flake-like particles have a cross-sectional structure with the AB planes laminated in a thickness direction. The spheroidal particles and the flake-like particles have an average particle size of 3 to 50 and 1 to 25 m respectively. K1 is 0.80 to 0.97 and K2 is greater than K1, and a difference K2 K1 is 0.03 to 0.15.

A cage assembly for a rolling bearing including an improved lubricant configuration is provided. The cage includes a first cage half including a first rim and a first plurality of webs, and a second cage half including a second rim and a second plurality of webs. The first and second cage halves are assembled together with end faces of the first and second plurality of webs contacting each other to define a plurality of rolling element pockets. A first side plate is fastened to the first rim of the first cage half. A second side plate is fastened to the second rim of the second cage half. Lubricant is located in a first reservoir defined by a first groove in either the first rim or first side plate and is also located in a second reservoir defined by a second groove in either the second rim or the second side plate.

A convertible bearing cage is provided including a first cage part having a first rim with a plurality of first projections extending axially therefrom that form open, snap-in pockets for receiving bearing balls. Connection holes are located in the projections. A second cage part having a second rim with a plurality of second projections extending axially therefrom that form partial pockets is also provided. The plurality of second projections are aligned with the first projections. A ring guide extends circumferentially around the second rim. The second cage part is connectable to the first cage part with the second plurality of projections contacting the first priority of projections using connection elements that engage in or through the connection holes to form closed pockets. The first cage part is used alone as an open pocket, ball guided cage, or connected to the second cage part as a closed pocket, ring guided cage.
