Rotary Joints Series 7950
Quick-Change Cartridge System
In extruder construction the rotary joints are normally integrated in cramped installation situations. For that reason slender and compact sizes are called for. On the basis of the proven sealing system of its 7900 series, Haag + Zeissler Maschinenelemente GmbH, Hanau, Germany, has now developed a compact rotary joint, taking into account economic aspects.
The robust, vibration-proof sealing cartridge system CD-Cartridge-Design of the 7950 series combines the rotor, bearings and the stationary and rotating sealing parts in a pre-assembled unit. This quick-change cartridge system can be individually and easily exchanged. In this way the machine downtimes can be minimized.
The housing of this rotary joint is made of anodised aluminum. The weight of the housing has been reduced by 60% through the choice of this material. This minimizes the oscillating mass at the shaft end and the service life of the rotary joint is prolonged.
Haag + Zeissler consistently manufactures the 7950 series only in Germany.
