A power actuated parallel gripper for engaging and holding a workpiece wherein a pair of linkage assemblies actuate a pair of jaws for linear reciprocal movement thereof and prohibit unpowered movement of the jaws from the clamped position. In the preferred embodiment, the configuration of the linkage assemblies provides for the clamping of an outer diameter of the workpiece. In a second embodiment, the configuration of the linkage assemblies may be manipulated to engage the internal diameter of the workpiece. The linear movement of the jaws is guided by a guide rod having a longitudinal axis substantially perpendicular to the longitudinal axis of the housing. The jaws cooperatively receive the guide rod through apertures provided in the jaws, and compression springs are utilized between the ends of the guide rod and the ends of the apertures provided in the jaws to maintain the position of the guide rod between the jaws.
