PURPOSE: A rotary joint used for a high-speed hot milling roller in the steel industry is provided to block the leaked cooling water from over-flowing toward a bearing installed in a main bearing housing. CONSTITUTION: A rotary joint used for a high-speed hot milling roller in the steel industry comprises a main bearing housing(2100), a bearing(2110), a roller(3000), a connector(1100), a casing(1200), a pipe(1300), and a mechanical seal unit(1400). The bearing is formed inside the main bearing housing. Both ends of the roller are pivotally supported on the bearing, and melted iron slips over the roller being rotated.
