Guidanceprecise gripping through flat, low-playprecision ground guidance along the entirelength of the housing

Base jawsfor the connection of workpiece-specificgripper fingers

Housingweight-reduced through the use of a hard-anodized, high-strength aluminum alloy

Kinematicswedge-hook principle for high powertransmission and centric gripping

Centering and mounting possibilitiesfor universal gripper assembly

The round piston is moved up or down by means of compressed air. Through itsangled active surfaces, the wedge hook transforms this motion into the lateral,synchronous gripping movement of both base jaws.

Function descriptionDue to the long guidance, the gripper is highly resistant during gripping operationswhen the gripper fingers are subject to high moment loads. Grippers with increasedexchange accuracy are available on request.

Options and special information

Sectional diagram



Gripping forceis the arithmetic total of the gripping force applied to each base jaw at distance P(see illustration), measured from the upper edge of the gripper.

Finger lengthis measured from the upper edge of the gripper housing in the direction of the mainaxis.

Repeat accuracyis defined as the spread of the limit position after 100 consecutive strokes.

Workpiece weightThe recommended workpiece weight is calculated for a force-type connection with acoefficient of friction of 0.1 and a safety factor of 2 against slippage of theworkpiece on acceleration due to gravity g. Considerably heavier workpiece weightsare permitted with form-fit gripping.

Closing and opening timesClosing and opening times are purely the times that the base jaws or fingers are inmotion. Valve switching times, hose filling times or PLC reaction times are notincluded in the above times and must be taken into consideration when determiningcycle times.

� Moments and forces apply per base jaw and may occursimultaneously. My may arise in addition to the momentgenerated by the gripping force itself. If the max.permitted finger weight is exceeded, it is imperative tothrottle the air pressure so that the jaw movement occurswithout any hitting or bouncing. Service life may reduce.

The FPS flexible position sensor can distinguish between five freely programmable rangesor switching points for the stroke of a gripper and can be used in conjunction with a PC asa measuring system.Description IDAS-PGF 50 0302731

The direct connection is used for supplying compressed air to the gripper without hoses.Instead, the pressure medium is fed through bore-holes in the mounting plate.
