Secure Gripping in Many Variants

Standard gripper series from Festo sets new standards

Technical updates are placing standard grippers from Festo in a leading position for mechanical engineering applications of tomorrow. The parallel, three-point, radial and angle grippers DHxS from Festo are compact and offer greater reliability in the gripping process.

HAUPPAUGE, NY - Standard grippers are the first choice for cost-effective, lightweight and compact construction of handling and assembly systems. The parallel, three-point, radial and angle gripper series DHxS from Festo features optimized gripping force retention and overload protection as well as integrated sensor slots. It offers increased reliability in a range of sizes and stroke lengths.


A number of forward-looking features ensure reliability and precision. The integrated fixed restrictor provides an effective safety buffer, protecting against overloading during high-speed gripper motions and preventing damage due to excessive forces. The integrated sensor slots in the medium and large sizes offer the advantage of cost-effective stroke sensing via sensors SMx. Their successful integration has resulted in a slim, compact design without any interference contours caused by external sensors. The new, compression spring-assisted gripping force retention provides more security in the event of a pressure failure. In addition, T-slot guides increase the torque resistance of the gripper jaws.

The double-acting piston drive gives the standard grippers stable kinematics and maximum repetition accuracy. A wide range of mounting options in the form of threaded, fitting and centering holes make the new generation of Festo standard grippers very flexible to mount.


The parallel and three-point grippers DHxS have lightweight aluminium housing with integrated receiving hole for the pneumatic piston. The force generated by the linear motion is transferred to the low-
backlash gripper jaws by means of lever kinematics. Since the lever is
indirectly in mesh with the two gripper jaws via a piston rod,
there is no need for additional synchronization.

The pneumatic pistons of the double-acting DHxS radial and angle grippers act on the gripper jaws, mounted on pivots in a gripper jaw guide, by means of a slotted guide system. As with parallel and three-point grippers, this means that there is no need for separate synchronization.
