Transportation and storage
Transportation
Use suitable lifting gear to transport rotary joints weighing more than 25 kg.
Storage
In the original packages, Maier rotary joints are not suited for a storage time of more
than 6 months.
In the case of extended shutdown or storage periods of rotary joints, it is recom-
mended to use suitable corrosion protection film as provided, for example, by Cortec
Corp. (www.CortecVCI.com).
The storage room must be free from dust, sufficiently ventilated and not subject to
major temperature changes (relative humidity below 65%, temperature between 15°C
and 30°C).
After a storage time of more than 2 years or when the package has been damaged or
the unit has been subjected to shocks, the rotary joint must be checked in the factory
or the nearest service center!
If you want to preserve complete system components including the rotary joint, make
sure the corrosion protection measures are compatible with the materials and sealing
elements used Risk of chemical reactions and accumulations at sealing and bearing
elements.

Information on design and mounting and operation
The following must be noted for fast and reliable mounting and commissioning, for safe
operation of the rotary joint and for ensuring that the warranty will not be void:
Never operate the rotary joint outside of the application and performance limits speci-
fied.
For smooth operation of rotary joint ensure concentricity and minimum run-out toler-
ance of roller and intermediate flange!
The information on the admissible mounting position of the rotary joint provided in the
section "Specifications and Spare Parts" must be adhered to.
For the connection, use flexible hoses between the supply system and the rotary joint
housing. This compensates for heat expansion and vibrations.
Never apply torsional, tensile or pressure loads to metal hoses. Observe the mini-
mum bending radius as specified by the manufacturer – if in doubt, contact your hose
vendor. Section 6.2 provides examples of possible hose installation.
Never use axial compensators.
Use flat packings made of pure graphite to securely seal flange connections.
Only operate the rotary joint with a sufficiently dimensioned torque support at the
housing. Use a locking pin or an anti-rotation fork. The support element must allow
for axial and radial movements of the housing.
