SG

Product catalog summary

Design Features
SG bar pullers are utilized for bar feeding and are positioned in the machine's tool holder. The clamping force is generated when the material to be pulled presses the clamping jaws apart against the spring force of the lever gear. The NG shanks are designed according to DIN 69880 or VDI guideline 3425, Page 2. A special connection allows the angular position of the shaft to be altered by 90°. If necessary, close location sleeves in the tool holder. Only use a bar puller of the SG..20 DIN series if the tool holder is designed for shank size NG20.

Konstruktionsmerkmale SG-Stangengreifer werden zum Vorziehen von Stangenmaterial verwendet und dazu im Werkzeugträger der Maschine positioniert. Die Spannkraft entsteht beim Auffahren auf das vorzuziehende Material, wenn es die Spannbacken gegen die Federkraft des Hebelgetriebes auseinanderdrückt.
