The present invention relates to a cryogenic swivel joint which can be easily maintained, and more particularly to a cryogenic swivel joint which is provided at a connecting portion of respective pipes of a loading arm used for unloading liquefied natural gas (LNG) Thereby preventing leakage of liquefied natural gas during operation. Particularly, according to the present invention, the cover is slidably coupled to the shaft, so that the flange and the shaft can be easily separated and combined, thereby facilitating replacement and maintenance of parts such as a seal. Further, in the present invention, the portion where the bearing is in contact with the shaft is formed as a separate guide, and the guide is easily separated when the cover is detached, so that the guide can be replaced by simple disassembly and assembly have. Accordingly, it is possible to improve the reliability and competitiveness in the field of loading and unloading of ship cargo, the field of loading or unloading cargo in liquid state, especially the loading rock cargo unloading cryogenic fluid cargo, have.
