An auger-type icemaker for producing hard chip ice of high quality comprises a refrigerated cylinder for forming ice grown on an inner wall surface thereof, a scraper auger rotatably mounted in the refrigerated cylinder for scraping off the ice on the inner wall surface of the refrigerated cylinder, and upper and lower bearing by which said scraper auger is rotatably supported in the refrigerated cylinder. The upper bearing has standard peripheral surfaces and a plurality of axial ribs projecting radially outwardly from the standard peripheral surfaces into abutment against the inner wall surface of the refrigerated cylinder. The standard surfaces include slant surfaces extending upwardly and radially outwardly progressively toward the inner wall surface of the refrigerated cylinder, and parallel surfaces extending upwardly contiguously from the slant surface and substantially parallel to the inner wall surface of the refrigerated cylinder.
