Airpot® Corp. (Norwalk, CT) announced GramForce™ Accurate Force Pneumatic grippers that generate no measurable friction and provide a gentle grip for delicate operations. They operate at pressures from 0.02 MPa to 0.7 MPa, and offer holding pressures as low as 0.25 N (0.056 pounds) and up to 8.6 N (1.9 pounds). With synchronous and counterbalanced parallel design that allows unchanging gripping force in any mounting orientation, the grippers are internally driven by two 5.6-mm-bore pneumatic actuators. The carriage blocks are mounted on a stainless steel rail. They have operating ranges from -20 to 80 °C. The design accommodates finger lengths up to 75 mm. Assembled, the gripper is less than 50 mm high, less than 79 mm long, and 26 mm wide. The grippers are suited for precision assembly equipment, test and measurement devices, robotic end-effectors, small parts handling, and machining operations.
