Press Release Summary:
GK Series is comprised of six 180° opening (2 x 90°) angular grippers suited for applications that must be performed within limited work area. Along with 0-180° stroke-limiting screws, product features gripping torques from 40-4,000 Ncm, C45 K steel jaws, and aluminum body. When jaws are completely opened, work piece can be freed without having to retract gripper. From open position, force generated by jaw tips increases as they near fully closed position and become self-locking.

180° Opening Angular Grippers Save You Time and Money
New Hyde Park, New York -- A new series of 6 180° opening angular grippers from Techno-Sommer Automatic is ideally suited for applications which must be performed within a limited work area. Identified as the GK Series, they feature stroke-limiting screws to adjust the stroke between 0° and 180° and have gripping torques ranging from 40 Ncm to 4000 Ncm.
When the jaws are completely opened, the work piece can be freed without having to retract the gripper. This saves valuable cycle time, as well as the expense of a retraction mechanism or a cylinder. From a fully open position, the force generated by the jaw tips increases as they near the fully closed position and become self-locking. Due to the design of the links, a tremendous closing force is generated. As the jaws open, the mechanism produces significantly greater velocity at the jaw tips than during the closing stroke. Therefore, if the jaws are long and heavy, a damping device or throttle valve may be necessary for the opening stroke. Switch-activating cams (trip dogs) on the face of the gripper fingers can be used as "open" or "closed" indicators. The internal linkages are guided by two side plates made from hard anodized aluminum. As a result, the gripper can handle large side forces. All of these units are double acting. There are two pairs of air fittings located on the front side of the gripper. The front connections are factory-sealed with removable plugs. Either pair of air fittings may be used, depending on the mounting constraints.
Threaded holes are provided for fastening the proximity switch mounting blocks. The jaws are made of C45 K steel, whereas all of the body is constructed from high-strength aluminum. All jaws are hard anodized and nickel-plated. This guarantees durability and light weight.
