Vibrations have a harmful effect on the accuracy of the workpiece or product being manufactured. If the vibrations become too strong this can cause damage to the plant, which usually leads to a further increase in the vibrations and ultimately to total failure.

No matter how precisely and rigidly the machine is manufactured or how firmly it stands – oscillations and vibrations can be reduced, but never entirely eliminated.

Rotary joints are required for feeding media (water, steam, oil, air, etc.) into rotating shafts, rollers or spindles.

They are usually positioned at the end of the rotating machine component and form the interface to the stationary pipelines. Rotary joints can be a cause of machine vibrations if their rotating parts are carelessly manufactured and/or if insufficient attention is paid to the connection to the rotating end of the shaft. Conical threads are ruled out here.

Haag + Zeissler offers the series 7101 of rotary joints for machines with unavoidable or intended rotary or translatory oscillations and vibrations. The weight has been reduced by 60%, prolonging the service life of the rotary joint.
