摘要： This slewing bearing 10 includes: an inner ring 11 having an inner-ring-side rolling-element rolling surface 12 on an outer peripheral surface; an outer ring 21 having an outer-ring-side rolling-element rolling surface 22 on an inner peripheral surface, and being arranged outside the inner ring 11 such that the outer-ring-side rolling-element rolling surface 22 faces the inner-ring-side rolling-element rolling surface 12; and a plurality of rolling elements 31 rollably disposed on a rolling-element rolling passage 28 formed by the inner-ring-side rolling-element rolling surface 12 and the outer-ring-side rolling-element rolling surface 22. Then, the inner ring 11 or the outer ring 21 is configured to have combination of a press-worked part having a contour shape formed by pressing work, and a removal-processed part including at least the inner-ring-side rolling-element rolling surface 12 or the outer-ring-side rolling-element rolling surface 22, formed by removal processing. Such a configuration makes it possible to provide a slewing bearing having a structure that can be manufactured at low cost while maintaining a certain performance.

摘要： An outer ring 6a for a shell-type radial needle bearing having a cylindrical shape with a bottom is achieved for which fatigue life of the bottom plate section 9a and the continuous section between the bottom plate section 9a and the cylindrical section 8a is improved, as well as the anti-corrosion characteristic of the outer ring 6a is improved and the outer ring 6a can be prevented from coming out of the bearing without an increase in cost. After obtaining an intermediate raw material 35 having a cylindrical section and a bottom plate section from a metal raw material, shot peening is performed on the intermediate material 35 to create residual compressive stress in the surface and surface layer section on the outer surface side of the cylindrical section 8a and the bottom plate section 9a such that the residual compressive stress in the surface layer section on the outer surface side is greater than the in the surface layer section on the inner surface side, and from the surface to a depth of 0.03 mm is 700 MPa to 1600 MPa.

摘要： This sliding bearing (3) comprises a pair of semicircular half bearings (12) formed into a cylindrical shape by bringing both circumferential ends thereof into contact with each other. The axial width of the half bearings (12) is narrower in both circumferential ends (12a) and the circumferential center (12b), and wider in the quarter parts (12c) located therebetween. During manufacturing of the half bearings (12), finishing by cutting processing is first performed on the parts of a flat-plate material (21) which after formation are to become the two axial-direction end faces (12d) and the two circumferential-direction end faces of the half bearings (12), and thereafter, the flat-plate material is deformed into a semicircle.

摘要： A halved sliding bearing (1) has a recess (7) formed in a circumferential direction from an outer peripheral edge of a mating surface (5) of a semi-cylindrical bearing main body (3). To prevent formation of a burr to an inside of the recess (7) during formation of the mating surface (5), an entirety of at least one edge segment of a peripheral edge of the recess (7) opening on a circumferential end surface of a semi-cylindrical member (23) as an unprocessed body of the bearing main body (3), the at least one edge segment intersecting with an axial direction of the member (23), is chamfered. The mating surface is formed by cutting the circumferential end surface such that a cutting blade (31) firstly reaches the chamfered edge in the peripheral edge of the recess (7). Thus, the bearing main body is produced.
