SERIES GRR GRIPPERGUARDIAN GRIPPERDesign Enhancements• 75% Higher moment capacity• 55% Higher grip force• 25% Higher speed• 10% Lower weight• Additional accessories• Continuous feedback jaw position sensor• Extensive engineering analysis and testing assureperformanceSTRESS ANALYSIS PLOT [psi]300002500020000150001000050000(HALF MODEL SHOWN)Major Benefits• Narrow width and a wide range of available jaw travels• Compact design provides high grip force and largemoment capacities with low overall weight.• Rugged build withstands high impact and shock loads.• Double acting for both internal and external gripping.• Unique dual air-passage piston rod design promotesrapid bore pressurization for short cycle times.• Three large diameter jaw guides spanning the length ofthe gripper provide stable jaw travel, long allowabletooling length, and high moment capacities.• TC fluoropolymer composite guide shaft bushingsprovide long life and smooth jaw travel in demandingindustrial environments.• Synchronizer is enclosed, protecting the mechanismfrom debris.• Non-synchronized and independently controlled jawsallow flexibility to support diverse applications.• Optional Rodlok ® locks the jaws in a stationary positionin the event air pressure is lost.• Optional analog output sensor continuously monitorsentire jaw travel. Gripper is “sensor ready” allowingthe sensor to be factory installed or easily installed inthe field.• Proximity switches are available for discrete indicationof jaw position.Industry Uses• Material handing of rolls, barrels, pallets, andcontainers• Movement of large sand and investment castings• Small engine block manufacture• Automotive, aeronautical, and agricultural wheelrim manufacture• Clamping and fixturing during assembly operations• Gaging and sorting of large parts and assemblies• Centering and registration of heavy parts• Incorporation into space-restricted processing andmanufacturing equipmentList marks of PHD which appear on promotional material are registered trademarks of PHD, Inc.SOLUTIONS FORINDUSTRIAL AUTOMATIONGRR03(800) 624-8511www.phdinc.com/grr5
