Gripper systems are indispensable for industrial robots or handling systems as they form the connection between the workpiece and the handling system. Grippers are operated pneumatically or electrically and are used for gripping, holding, positioning and orienting the workpiece or tool. Normally, gripper systems are mounted on the outermost or last axis of handling systems and are connected to the main power cable.
Mechanical grippers from Festo are moved by an internal drive and transform the drive motion into a gripping motion. This movement of the gripper jaws is referred to as a stroke. Depending on the stroke and gripping force, workpieces of different sizes can be gripped and handled. Grippers with a long stroke are offered by Festo in both pneumatic and electric versions.
