Bearing bush

A bearing bush for supporting a motor vehicle part, the bearing bush comprising:

• an inner tube comprised of a metal,
• a sliding sleeve comprised of a first plastic material and mounted rotatably on the inner tube, and
• an elastomer bearing that surrounds the sliding sleeve and has at least a first elastomer body and an outer sleeve,
• wherein a sliding layer comprised of a second plastic material is disposed on an outer circumferential surface of the inner tube, the first plastic material and the second plastic material forming a tribological pairing either of two different polymers from the groups of polyamides, polyoxymethylenes, polyketones, fluoropolymers, polyethylene terephthalates or polybutylene terephthalates, or the tribological pairing being formed from polyketone against polyketone, and wherein the polymers of the tribological pairings each are present in a continuous thermoplastic polymer phase;
• and the sliding layer is applied to the inner tube by powder coating.
