HAAG + ZEISSLER Maschinenelemente GmbH presents a new series for pneumatic use. These rotary joints enable valve controllers or cylinders on rotating machine parts to be supplied with compressed air or vacuum. Applications for this type of rotary joint are to be found, for example, in turntables, transfer machines or automatic assembly machines. The standard versions are equipped with 2, 4, 6 or 8 channels in the connection sizes M5 and ¼”. The rotary joints have been developed with a modular segmental design, so that the seals are easily accessible and thus simple to replace. The maximum speed of rotation is 250 rpm and the maximum operating temperature 90 °C. The multiport rotary joints can be used both for air and for vacuum. In addition, electrical signals, media or supply lines can be fed through the central bore. The inclusion of ball bearings ensures a long service life under high stress. The materials used are steel, stainless steel or aluminium, depending on the application and version.
