CAGE, ANTI-FRICTION BEARING, MACHINE TOOL, AND METHOD OF MANUFACTURING CAGE

摘要

A cage (14) consists of a magnesium alloy part. This magnesium alloy part is injection-molded using a mold (60) which is provided with a cavity section (61) having a shape that corresponds to the shape of the cage (14). The magnesium alloy part has a shape such that it is necessary to perform forced removal from the mold (60). Due to the above, it is possible to obtain the cage (14), which consists of a magnesium alloy part having high strength and which has a shape such that it is necessary to perform forced removal from the mold (60); an anti-friction bearing provided with the cage (14); a machine tool provided with the anti-friction bearing; and a method of manufacturing the cage (14).
