Abstract: The invention relates to a chain guide, respectively a chain tensioner for use in a lubricated sliding system, comprising a surface layer or bearing or comprising a sliding element comprising a surface layer, the surface layer being mainly made of a polymeric material containing a matrix polymer and optionally other components dispersed in said matrix polymer, wherein the matrix polymer consists of a semi-crystalline polyamide (SCPA) having a tensile modulus at 140° C. of at least 800 MPa (measured by the method according to ISO 527-1A). The invention also relates to a power train drive system comprising an engine, a transmission differential and a drive shaft system, a drive chain and a plastic component comprising a sliding element in contact with the lubricated drive chain, wherein the chain guide, the chain tensioner, respectively the sliding element has a coefficient of friction (CoF), measured in lubrication oil at 140° C. at a nominal contact pressure of 1 MPa and a speed of 1 m/s, of at most 0.07.
