Flexible in use, robust and low-maintenance: The universal rotary joints of the H series are designed for a wide range of media as well as a large pressure and temperature range up to medium speeds. This means that you only need one solution for a wide range of applications. As a result, you sustainably reduce your costs for maintenance and warehousing.

Your advantages
Simple
connection
The housing is mounted on the rotating rotor and is self-supporting. This eliminates the need to attach the housing to the surrounding structure. The rotary joint is precisely centered to the roller via the slider connection.
Low
repair effort
H series rotary joints are constructed from few individual parts with high availability. This enables repair without special tools at your site. You also save on storage costs, as you only need to stock wear parts.
Flexible
modular system
You assemble your rotary joint from individual components and adapt it individually to your requirements. Depending on your needs, you can, for example, change the position of the locking device or subsequently screw in flat-sealing housing flanges.
Ideal for
high temperatures
An optional nitrogen blanket helps to keep out atmospheric oxygen and thus prevent cracking of the heat transfer oil.
Maintenance-free
Self-lubricating carbon plain bearings reduce maintenance effort and costs. No greasing or re-greasing necessary during operation.
No shrinkage
necessary
For applications at low speeds and pressures, the sealing rings can already be ground in at the factory. As a result, the rotating unions operates leak-free from the start.
Higher plant availability
by wear indication
As the carbon seal ring wears, a circumferential groove appears on the rotor. You recognize upcoming maintenance and can plan in good time.
No unscrewing
for counterclockwise rotation
HWX series rotary joints with a nominal size of 65-100 have a clamping nut for the inner pipe in the housing. For left-turning rolls, the inner tube is clamped from the outside if required.
Also with
ATEX certification
For use in potentially explosive areas, we offer special versions with ATEX certification.
