To provide a rolling bearing for slide door, which comprises an outer coating member having heat resistance and creep resistance and also capable of securing sufficient durability (abrasion resistance).SOLUTION: A rolling bearing for slide door comprises an inner ring, an outer ring, a plurality of rolling bodies rotatably arranged in an annular space between the inner ring and outer ring, and an outer coating member provided so as to cover an outer peripheral surface of the outer ring and composed of a resin composite. The resin composite contains polyamide 66 and aramid fiber. The polyamide 66 uses HFIP as solvent, and a number average molecular weight measured by a gel permeation chromatography method with PMMA as standard substance is within a range of 34000-60000. The content of the aramid fiber is within a range of 5-25 mass%.SELECTED DRAWING: Figure 1
