of the same composition for a dry film lubricant and a sliding or radial bearing having a sliding layer using

The present invention provides a sliding bearing having improved storage properties, particularly anti-seizure property, initial conformability and cavitation resistance. According to the present invention, a sliding layer (2) on a surface of a bearing alloy layer (1) consisting of a copper based or aluminum-based alloy is provided, wherein ( "thereby"), the sliding layer (2) is structured so that a polyamide-imide resin as a main component a polyamide resin is added and mixed under a high shear force, wherein a polymerlegiertes resin binder is formed, in which 1 to 75 mass% of a solid lubricant dispersed. The sliding layer (2) can have high toughness and strength, as well as improved anti-'Festfresseigenschaft, initial conformability and cavitation resistance.
