Abstract
A bush bearing having an outer lubricating layer, a manufacturing method therefor and a scroll compressor having same applied thereto, according to the present disclosure, includes a bush bearing comprising: a base member which has a cylindrical shape having no separated surfaces along the circumferential direction; and a lubricating member which is formed from a material having a lower rigidity and more excellent lubricity than the base member, and has a cylindrical shape having no separated surfaces along the circumferential direction by being integrally provided to the outer circumferential surface of the base member, wherein the cylindricity of the outer circumferential surface of the lubricating member satisfies a value that is within 0.6% of the average thickness of the lubricating member, and the lubricating member has carbon fiber contained in a resin base, wherein the carbon fiber has cut surfaces exposed on both ends of the lubricating member.
