Operation
A double-acting pneumatic cylinder drives aninternal linkage. The jaws move concentricallyand are connected to the center section bylinks (pivoting arms).
The jaws of the grippers can be machined in many differentways, for example, drilling, turning or milling.
So simple it’s scaryDue to its slim design, it doesn’t need muchspace. By changing the pin linkage configuration,the gripper can be changed from air-closing andspring-opening to air-opening and spring-clos-ing. The jaws are made of steel and the face canbe machined up to 10 mm (12 mm in case of theGM16). Depending on the form of the workpiece, the jaw can be turned, milled or drilled asshown in the examples. On the GM10 and GM16,the air connections are on the front and side. TheGM16 is also available in a double-acting version(without spring) for fast cycles - see GM16D. Onthis model, the two air connections are locatedon the front. Sensing is not possible due to thesmall size of these grippers; it must be done bymeans of valves. A special gripper, the double-acting GM22D is available as a larger and morepowerful size without a spring (closing force =55 Ncm, opening force = 30 Ncm). A drawing isavailable upon request.
By the way:The GM10 is supplied with a spacer with whichthe gripper fingers can be set exactly parallel formachining. On the GM16, this function isassumed by the grub screw in the right-handjaw.

things worth knowing
Basic explanations
FunctionDrive GM10, GM16: single-acting cylinder with spring returnDrive GM16D, GM22D: double-acting pneumatic cylinder with integrated spring as grip force safety devicePower transfer: toggle type linkageMaterial Housing: hard-anodized aluminum Functional parts: steel MaintenanceRecommended at: 1.5 million cyclesActuation: filtered high-pressure air (10 µm), dry or oiled maintenance of the mechanics:Maintenance of the mechanics – see owners’ manual –
Grip force safety device: required during pressure loss for maintaining position of workpiece – pneumatic/hydraulic: through pressure retention (one-way valve required DSV1/8)– mechanical: through spring pre-tension– spring power: specifications based on minimum spring pre-tension Total power: arithmetic sum of the individual elements on the gripper jaws Closing and opening times: required time for the gripper jaws to cover the maximum stroke lengthSchematic: displays static forces and momenta that can additionally affect grip force
