VH = work stroke, RH = back stroke

Design:

Cylinder barrel from steel, burnished. Piston case hardened and ground. Piston rod is supplied as standard with HC threads. lf a piston rod with internal thread is desired, a HELI-COIL insert (diameter x1.5) is screwed into the HC thread. Oil supply via threaded port.

Application:

Particularly suitable for retrofitting existing fixtures for hydraulic actuation. When workpieces are clamped onto a machine tool table, the hollow rod cylinder can be fitted over the clamp bolt instead of the nut. The hollow rod cylinders can be used for push or pull applications.

Note:

Cylinders are designed for use in combination with tempered bolts, material grade 12.9 (e.g. DIN 787). Threaded body provides a wide range of adjustability. Suitable flange nuts DIN 70852.
