3. The slide bearing according to claim 1 , wherein the base layer is made of metal.

4. The slide bearing according to claim 1 , wherein the sliding layer and/or the second slide body has at least one additive.

5. The slide bearing according to claim 4 , wherein the additive comprises polytetrafluoroethylene, MoS2, silicone oils, graphite, graphene, carbon nanofibres and/or carbon nanotubes.

6. The slide bearing according to claim 1 , wherein an adhesive layer is included between the base layer and the sliding layer.

7. The slide bearing according to claim 1 , wherein the first slide body has at least one breakthrough.

8. The slide bearing according to claim 1 , wherein the first slide body and/or the second slide body has an axial slide body section for absorbing axial forces and/or a radial slide body section for absorbing radial forces.

9. The slide bearing according to claim 8 , wherein the first slide body and/or the second slide body is of annular and/or hat-shaped design in which the respective radial slide body section extends from the respective axial slide body section.

10. The slide bearing according to claim 1 , wherein the first slide body has a first slide ring for absorbing radial forces and/or the second slide body has a second slide ring for absorbing radial forces.

11. The slide bearing according to claim 1 , wherein a lubricant is provided between the first slide body and the second slide body.

12. The slide bearing according to claim 11 , wherein the lubricant is a grease having a consistency index of between approximately 1 and approximately 4.

13. The slide bearing according to claim 11 , wherein the lubricant is a grease having a consistency index of between approximately 2 and approximately 3.

14. The slide bearing according to claim 1 , wherein at least one recess, at least one bead, at least one groove and/or one structuring is provided in the first slide body and/or in the second slide body.

15. The slide bearing according to claim 1 , wherein at least one of:

the first slide body and/or the second slide body is connected in a form-fitting, force-fitting and/or material-fitting manner to the first housing part; and

the second slide body is connected in a form-fitting, force-fitting and/or material-fitting manner to the second housing part.

16. The slide bearing according to claim 1 , wherein the first housing part and/or the second housing part is made of plastic.

17. A method for producing a slide bearing, comprising:

injection moulding or aluminum die casting a first housing part and a second housing part, each made of plastic or aluminum;

connecting in a form-fitting, force-fitting and/or material-fitting manner a first slide body with the first housing part, and a second slide body made of plastic with the second housing part; and

connecting the two housing parts so that the two slide bodies abut slidably against each other;

wherein the first slide body is produced from a hybrid material by:

providing a metallic base layer;

transforming the base layer to a disc-shaped or hat-shaped body having an annular disc and a sleeve-shaped section extending therefrom;

applying a powdered plastic or powdered plastic compound forming a sliding layer to at least a portion of the base layer by electrostatic powder coating to form a degree of crystallinity of at least 80% of the coating polymer's maximum theoretical crystallinity on a surface of the sliding layer; and

melting and cooling of the plastic or plastic compound to form the sliding layer;

wherein the sliding layer and the second slide body form a sliding pairing, each of the sliding layer and the second slide body made of a polymer present in a continuous, thermoplastic polymer phase, and one of:

the polymers of the sliding layer and the second slide body are different polymers from the groups of polyamides (PA), polyoxymethylenes (POM), polyketones (PK), polytetrafluoroethylenes (PTFE), polyethylene terephthalates (PET) or polybutylene terephthalates (PBT) such that the sliding pairing is made of two different polymers, or
