A method of forming a component from a powder metal includes forming the component to a desired shape from the powder metal, heating the component to a burnishing temperature of 900 to 1300 degrees Fahrenheit, and burnishing a surface of the component while the component is at the burnishing temperature to densify the surface.

The present invention provides a method for manufacturing an air bearing with discreet orifices designed to facilitate a non-contact interface between surfaces. The process involves using a mold wherein wires or filaments are placed to form air channels within a cast. Various materials, such as silicone, steel, and composites, can be used for the mold. After casting and curing the material, the wires are removed, leaving precisely defined channels that allow air to flow through, creating a cushion of air that maintains a gap between the bearing and the surface it operates on. This gap can be adjusted by changing the air pressure or the number of channels. The bearing components may be further machined or secured in a housing connected to an air source, enabling the bearing to hover and operate efficiently in various applications. The invention allows for multiple configurations of the air channels to optimize airflow distribution as required.

A ball joint having a ball pin and a housing. The ball pin together with the ball is accommodated in the housing to move in a rotational and pivotal manner. The ball is at least partially surrounded by a structural component. The structural component is essentially formed from a fiber-plastic composite structure and at least partially forms the housing.

A bearing cage or bearing cage segment is disclosed, in particular for a rolling-element bearing, wherein the bearing cage includes a polyetheretherketone (PEEK) base material having a low and medium viscosity, and less than 30%, in particular 15% to 25%, reinforcing material is added to the base material, and the reinforced PEEK material has a shrinkage in the melt-flow direction that falls in the range of 0.4% to 0.6%.

A cylinder head cover and a method for producing a cylinder head cover are disclosed. The method for producing a cylinder head cover may include: providing at least two metallic bearing bridges including a respective through-opening for mounting at least one camshaft and aligning the respective through-opening of the at least two bearing bridges axially relative to one another; connecting at least one metallic connection element to the at least two bearing bridges in a fixed manner so that the at least two bearing bridges are fixed and aligned relative to one another; and at least partially overmoulding the at least two bearing bridges and the at least one connection element with a plastic material.

A cage includes: an annular body having pocket holes for receiving balls; and a resin portion formed through injection molding of a resin containing a solid lubricant with the body being set as an insert component. The resin portion includes: first parts formed along inner peripheral surfaces of the pocket holes of the body to form pocket surfaces to be held in sliding contact respectively with the balls; and a second part formed along an outer peripheral surface (or inner peripheral surface) of the body to form a guide surface to be held in sliding contact with an outer ring (or inner ring). The first parts and the second part are formed integrally with each other. Weld lines of the resin portion are formed at positions of avoiding exposure of the weld lines at both end portions of the pocket surfaces in a cage circumferential direction.

A ball retainer for a slide apparatus and a mold for manufacturing the same. The ball retainer includes, in a width direction, a first extension part and a second extension part that are extended from a center line, forming a pre-determined angle with each other, in a length direction, a body part formed in the center, and a pair of holding parts. Each holding part is respectively formed at each end of the body part. Each holding part includes a plurality of ball insertion grooves for inserting balls that are spaced apart in the length direction. Expansion parts each having an expanding cross-sectional area are respectively formed at both sides in the length direction of the first extension part and the second extension part.

A rolling-element bearing assembly includes a bearing ring and a flange. The bearing ring has a surface including at least one circumferential groove extending at least partially around the bearing ring, and the flange projects radially inwardly or radially outwardly from the surface and has a flange section at a radially inner edge or radially outer edge of the flange that projects into the groove. A hardened casting material secures the flange to the surface.

A component part has an over-molded integrally formed insert member. The insert member has a predetermined feature. In addition, an end portion of the predetermined feature is exposed and free from over-molding.

The present invention is intended to provide a manufacturing method of a protective cover having a sensor holder part that has high adhesion strength between a metallic component and a plastic component and maintains high reliability over a long period of time.

The manufacturing method includes: a step of applying a thermoset resin adhesive to a surface of a metallic component 1A including a joining surface relative to a plastic component; a drying and solidification step of evaporating a solvent contained in the adhesive under a temperature condition at a temperature lower than a temperature at which the adhesive starts cross-linking reaction; and an injection molding step of placing the metallic component 1A as an insert in dies 18 and 19 and injecting a molten plastic material from a gate 20 into cavities.
