Provided is a support bearing for submersible motor constructed such that a noise prevention member is fitted to the exterior of the support bearing to reduce a noise caused by rotation of the support bearing. The submersible motor has an impeller installed at a bottom surface of a heat tank of a hot water circulation pump and forcibly impelling a hot water supplied from the heat tank to a destination, a motor housing installed under the impeller and having a shaft rotating the impeller by external power source, and an end cap installed under the motor housing. The end cap has an insertion groove at inner center, and a support bearing contacting with a lower end of the shaft is inserted in the insertion groove. A noise prevention member is fitted to an outer circumferential surface of the support bearing and prevents formation of a gap between the support bearing and the insertion groove.
