軸受のシール取付構造。 A swing bearing interposed between a rotating body and a base on which the rotating body is mounted, which has an annular groove formed on the outer circumferential side of the inner ring and the inner circumferential side of the outer ring. In a seal mounting structure for a slewing bearing in a construction machine in which an annular seal is fitted and fixed, the groove is formed on the outer peripheral surface of the inner ring and on the joint surface with the base, and the groove is formed on the inner peripheral surface of the outer ring. The insertion portion of the seal is formed in the joint surface with the rotating body, and the inner ring and the base, and the outer ring and the rotating body are attached to these grooves, so that the insertion portion of the seal is elastically deformed and attached. Seal mounting structure for slewing bearings in construction machinery.
