Base jawsfor the connection of workpiece-specificgripper fingers

Center borefor the feed-through of workpieces, for sensorsystems or optical workpiece recognition

Kinematicswedge-hook principle for high powertransmission and synchronized gripping

T-slot guidancehigh load-bearing T-slot base jaw guide withminimum play

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

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 horizontal,synchronous movement of the base jaws.

Function descriptionWith its center bore, the PZB series is the ideal standard solution for many areas ofapplication.

Options and special information

Sectional diagram



Gripping forceis the arithmetic total of the gripping force applied to each claw 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.
