Steam Joints are sealing components between a steam pipe and a rotation assembly such as a shaft, cylinder or roller. The joint seals water, steam and oils. Further, it neutralises swing, pendular and tumbling motion. This functionality is normally achieved with a concave or convex seal ring surface which is pressed against the sealing surface with a spring. Certain configurations also have a cylindrical wearing surface. Steam Joints are exposed to all known lubrication conditions including wet, mixed and dry running.
