Rotary joints series 7950 for extruder construction
The slender rotary joints from the HAAG + ZEISSLER 7900 series have proven themselves over a period of many years. At the request of our customers with the 7950 series a compact rotary joint has now been designed especially for cramped mounting spaces in extruder construction.
The slender rotary joints from the HAAG + ZEISSLER 7900 series have proven themselves over a period of many years. At the request of our customers with the 7950 series a compact rotary joint has now been designed especially for cramped mounting spaces in extruder construction.
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 has now developed a compact rotary joint, taking into account economic aspects. In its robust, vibration-proof sealing cartridge system CD-Cartridge-Design the rotor, bearings and the stationary and rotating sealing parts are combined in a pre-assembled unit.
This quick-change cartridge system can be individually and easily exchanged. In this way the machine downtimes can be minimised.
The housing of this rotary joint is made of anodised aluminium. The weight of the housing has been reduced by 60% through the choice of this material. This minimises 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. The rotary joints - made in Germany - are developed in the factory in Hanau with the goal of individually optimising the product for the complex requirements of the machine user.
