Abstract
A rotary joint for supplying and/or removing a fluid heat transfer medium to/from a rapidly rotating roll or drum supported upon journals. The rotary joint nipple threads into the journal bore and closely fitting complementarily shaped cylindrical surfaces on the journal end and joint nipple interengage to concentrically relate the joint to the journal, and engaging radial surfaces on the journal and nipple further coaxially position the joint with respect to the journal to prevent relative tilting. In an embodiment the joint nipple includes an internal seal ring axially biased against a counterseat to reduce the rotary joint axial dimension and permit utilization of wider spaced bearings which improves stability, balances bearing loads and increases bearing life.
