Abstract: A method of producing thrust washers in which a blank material in the form of a flat bar is forced to pass between an upper and a lower forming rolls arranged as a pair. The blank material is pressed onto one of the forming rolls to be bent in the breadthwise direction to become a thrust washer. The upper and the lower rolls cooperate with each other in defining therebetween a groove having a configuration corresponding to the cross section of the article to be obtained, through which the blank is made to pass. This method ensures an economical production of ring-shaped or arcuately shaped articles having accurate dimensions.

Abstract: There is provided a half thrust bearing having a constant bearing wall thickness between a slide surface and a back surface, and including an approximately flat center region and two end regions on both circumferential sides of the center region. Each end region extends from each circumferential end of the half thrust bearing toward a circumferential center over a circumferential angle of 5° or more and 35° or less. A reference surface is defined as an imaginary plane which is perpendicular to an axial direction of the half thrust bearing, parallel to the slide surface in the center region, and located away from the slide surface. An axial distance between the slide surface and the reference surface is minimum in the center region, and continuously increases circumferentially from a center region side toward a circumferential end side at any radial position in each end regions.

Abstract: A sliding member includes a resin overlay layer on a sliding-surface side of a bearing alloy layer. The resin layer includes a resin binder and 20% by volume or more of solid lubricant particles with an anisotropic shape dispersed in the resin binder. The sliding surface is located at 0° and has a virtual axis perpendicular to the sliding surface at 90°. An angle θ is formed by a straight line and a major axis of the particles. The total number of the particles in a observation region is N. A rate R1=N1/N of the number N1 of first particles at the angle θ of 70°≤θ≤90° from among the particles is 3%≤R1≤20%, and a rate R2=N2/N of the number N2 of second particles with the angle θ being θ≤20° is 35%≤R2≤65%.

Abstract: A sliding member includes a base material and an alloy layer that includes Cu as a main component and Bi and having a sliding surface formed on a side opposite to the base material. The alloy layer has a first region and a second region. The first region is set to a region taking up 30% of the thickness of the alloy layer which is from an interface in contact with the base material toward the sliding surface. The second region is set to a region taking up 10% of the thickness of the alloy layer which is from the sliding surface toward the base material. A larger number of Bi phases having larger cross-sectional areas are distributed in an arbitrary observation cross section as Bi phases included in the second region compared to Bi phases included in the first region.
