Abstract: The invention relates to a polyamide-based surface material having fillers which improve the tribologically active properties, wherein the fillers comprise at least one metal sulfide and/or calcium phosphate. The invention further relates to a three-dimensional molded body consisting of a surface material, produced, in particular, as an injection-molded part or extrusion part and or by additive fabrication.

Abstract: The invention relates to a polyamide-based sliding material, having fillers that improve the tribological properties, wherein the fillers comprise at least one metal sulfide and/or calcium phosphate. The invention further relates to a plain-bearing composite material, having a metal support layer, in particular made of steel or bronze, optionally a porous carrier layer, in particular made of bronze, and a sliding material, which fills the pores in the carrier layer, and to a three-dimensional shaped body for sliding load, consisting of a sliding material, in particular produced as an injection-molded or extrusion part and/or by additive manufacturing.

Abstract: The invention relates to a cam ring (2) for an injection pump for an internal combustion engine, comprising a round opening (4) for a shaft section, which can be eccentrically driven, and comprising a flattened outer section (6) against which a displacer element of the injection pump can be supported. A bush-shaped low-friction bearing means (12) for mounting the shaft section is provided inside the opening (4) of the cam ring (2). In order to reduce the problematic effects of pressing in the low-friction bearing means into the opening, the cam ring is designed so that the low-friction bearing means (12) in one form comprises a polymer-based bearing coating material (14) with friction-reducing fillers, which is directly placed upon the surface (16) of the cam ring (2) that delimits the opening (4).
