Sealing device

An industrial robot comprising at least one joint and a sealing device for providing a fluid-tight sealing of the joint, wherein the joint has a first part and a second part with a relative movement in between, the sealing device comprising:

• an outer sealing part designed to contact the first part and the second part, the outer sealing part includes a first outer side face designed to abut a first face of the first art and a second outer side face designed to abut a first face of the second part,
• an inner sealing part designed to contact the first part and the second part, the inner sealing part includes a third outer side face designed to abut a second face of the first art and a fourth outer side face designed to abut a second face of the second part,
• a spacing structure connecting the outer sealing part and the inner sealing part and having a plurality of radially extending spacing elements,
• wherein the outer sealing part and the inner sealing part define an annular intermediate space between the outer sealing part and the inner sealing part, wherein the outer sealing part and the inner sealing part are configured to seal off the annular intermediate space from both an exterior and an interior of the joint,
• wherein the annular intermediate space is configured to be in fluid contact with both the first part and the second part, and
• wherein the sealing device is made in one piece.
