The MHSH3 Series, 3-finger grippers adds a center through-hole to accommodate a push actuator to ensure proper release of work pieces. These are optimal for gripping spherical, cylindrical or round work pieces and loading or unloading of work pieces from the chuck of a machine tool. Its wedge cam design minimizes its overall size while retaining a high holding force making it suitable for end-of-arm (end effector) or space constrained pick and place applications.
