Cylinder barrel from steel, hardened and burnished. Piston rod hardened and chrome plated. Piston rod with internal thread. O-ring for flange seal. Wiper at piston rod. Oil supply via threaded connection or oil channel in the fixture body.


Universal Push-Pull Cylinder for various applications.


Various thrust pieces can be attached in the tapped piston rod ends. Clamps can be attached, as with the swing clamps.


The piston is guided, therefore, the max. permissable oil flow rate Q max must be observed in order to protect the mechanism. No force must be introduced at the piston when mounting accessory. The system has to be completely vented during installation. To control the oil feed, the throttle/check valve no. 6916-12-04 can be optionally used.


- Increase in the number of balls and slots to 3 to achieve a higher positioning accuracy and repetition accuracy. Also prolongs service life.
- More precise guidance
- contact force of balls into groove increased, thus guaranteeing highly-precise guidance over a long period of us.
- V-profile of the ball running groove guarantees a deeper ball run in the groove wall than at the groove edge.
- New materials for prolonging the service life of piston rod and guide.
