Roll line in a continuous caster

A roller line for transporting steel in a continuous caster, the roller line comprising:

• at least two roller line segments arranged along an axial line each roller line segment including a roller body configured to be in supportive contact with the steel and having two shaft ends, at least two bearings each configured to support a separate shaft end of the roller body, and two bearing housings each configured to house a separate one of the bearings
• a ring having a through-hole, each roller body of the two roller line segments having one shaft end at least partly disposed inside the through-hole of the ring, the two shaft ends disposed within the ring being at least generally adjacent,
• at least one torque transferring element configured to connect the two adjacent shaft ends,
• wherein the ring further has a closed compartment configured to receive lubricant for lubricating the at least one torque transferring element, the closed compartment being defined in the through-hole and sealed off by sealing elements located between the ring and circumferential surfaces of the first and second adjacent shaft ends, and
• wherein a relative axial movement is allowed between at least one of the sealing elements and one of the surfaces in which the at least one sealing element is sealing against.
