Abstract: A bearing bush and a method of manufacturing a bearing bush is provided. The bearing bush may be used in a transverse control arm. The bearing bush includes an inner sleeve; an outer sleeve arranged radially around the inner sleeve; an elastomer body arranged between the inner sleeve and the outer sleeve; and an intermediate sleeve which is, at least in sections, embedded in the elastomer body. The outer sleeve has, at its axial ends, a radially inwardly bent bend portion; wherein a radial outer surface of the intermediate sleeve has a radially outwardly directed bulge along the axial direction of the bearing bush. The intermediate sleeve has a radially outwardly protruding outer stop portion which forms an axial stop with respect to an axial inner surface of the bend portion of the outer sleeve.

Abstract: A bearing and/or seal assembly where pressurized gas (e.g., air) may be arranged to produce a contact-free bearing and/or seal is provided. The assembly includes a permeable body (12) including structural features (13) selectively engineered to convey a pressurized gas (Ps) from an inlet side (20) side of the permeable body to an outlet side (22) of the permeable body to form an annular film of the pressurized gas relative to the rotatable shaft. Disclosed embodiments may be produced by way of three-dimensional (3D) Printing/Additive Manufacturing (AM) technologies with practically no manufacturing variability; and may also cost-effectively and reliably benefit from the relatively complex geometries and the features and/or conduits that may be involved to, for example, form the desired distribution pattern or impart a desired directionality to the pressurized gas conveyed through the permeable body of the bearing and/or seal assembly.

Abstract: Provided is a sliding component having a low coefficient of friction and capable of exerting stable sliding characteristics from the initial stage of sliding, and a manufacturing method capable of easily manufacturing the sliding component. A sliding component (1) includes an iron substrate (10), in which graphite particles (13) are dispersed in an iron base (11), and a tin coating (20) formed on the iron substrate (10), the tin coating (20) including tin as a main material. The graphite particles (13) of the sliding component (1) are exposed through the tin coating (20). The manufacturing method includes: a preparation step of preparing an iron substrate (10) including graphite particles (13) dispersed in an iron base (11); and a film forming step of forming a tin coating (20) on the surface of the iron substrate (10), the tin coating (20) including tin as a main material. The film forming step forms the tin coating (20) so that the graphite particles (13) are exposed through the tin coating (20).

Abstract: Various teachings herein may be used to make a bearing bush for a rotating shaft, wherein a wall of the bearing bush has a wall thickness which amounts to less than 10% of the diameter of the bearing bush. In the axial direction, the bearing bush is made from a plurality of layers connected with a material bond. Each layer has a layer thickness between 10 μm and 200 μm and the wall has closed cavities which are filled with a powder.

Abstract: A valve and a bearing surface for a valve and a manufacturing method of the same including a valve body with a main channel extending between a fluid inlet and a fluid outlet, and a closing member provided in the main channel. The valve further includes a shaft connected to the closing member for moving the closing member between an open and a closed position. Moreover, the valve includes at least one bearing surface between the valve body and the closing member or the valve body and the shaft, the bearing surface further including a plurality of cavities filled with solid lubricant. An advantage of the claimed valve is that the lubricant is maintained longer on the bearing surfaces and thus lubrication periods and valve lifetime are increased.
