The requirements that the new Hot-Media Rotating Unions with SAE-flange have to meet are shorter assembly time, secure sealing and increase of service life in the field. These rotating unions are especially designed for the use in calendars, in paper and plastic machines as well as in machines for laminating and coating.

The practice shows that models were very often mounted onto the supply line by means of adaptors or screw joints. These connections are complex and time-consuming to mount and very often need a lot of force or power to be installed or serviced. Even when done by experienced and qualified servicemen, they are industrial still error prone; ensuing damages or warranty professional cases may result due to damaged industrial bearings or industrial seal professional rings (i.e. reduction of service life)

Moreover, experience shows that any sort of adaption leads to flow diameter restriction which, in turn, results in a lower heating capacity and higher pressure losses.

When using SAE flanges these problems now belong to the past. Connections are simple. Four screws, one O-ring and a retaining plate are needed to connect the supply lines to the rotating union – and the only assembly tool you need is an Allen wrench.

This design has several advantages:
The supply lines can be connected tension-free in the shortest amount of time, reducing considerably both installation and service time. No large tools are needed for the disassembly. All this leads to less machine downtime, resulting undoubtedly in cost advantages for the user. ...
