Festo GR-34 Parallel Gripper | 34 mm Bore, Pneumatic, Angular, 2-Finger, 150N Specs

Festo GR-34 pneumatic gripper specifications. 34 mm cylinder bore, angular gripper, 2-finger parallel motion, 150N gripping force. For pick-and-place and automation.

Product Overview

The Festo GR-34​ is a pneumatic parallel gripper​ from Festo's modular gripping system, designed for industrial automation and robotic applications. This gripper features a 34 mm cylinder bore, provides 150N maximum gripping force, and uses an angular design for parallel jaw movement. The "GR-34" designation indicates the gripper model with 34 mm bore size. This component provides reliable gripping and handling of workpieces in pick-and-place, assembly, and material handling applications with precise parallel jaw guidance.

Technical Specifications

Note: Specifications are based on typical Festo GR-34 gripper documentation. Gripping force, stroke, and weight are for standard configurations. Actual values may vary with specific jaw type and options.

Important Technical Notes

1. Pressure Rating:​ Do not exceed maximum operating pressure of 8 bar. Standard operating pressure is 4-6 bar for optimal performance and longevity.

2. Air Quality:​ Use filtered compressed air (40 µm). The gripper can operate with lubricated or non-lubricated air. If using non-lubricated air, ensure consistent air quality.

3. Gripping Force Calculation:​ Calculate required gripping force considering workpiece weight, acceleration, friction coefficient, and safety factor (typically 2-3x).

4. Jaw Selection:​ Choose appropriate jaws for your application. Consider workpiece geometry, material, and required grip points. Custom jaws are available for special applications.

5. Sensing:​ For position feedback, install appropriate sensors (reed or inductive) in the prepared sensor slots. Adjust switching points as needed.

6. Mounting:​ Ensure proper mounting surface flatness and use recommended torque values for mounting screws. Improper mounting can affect accuracy and lifespan.

7. Maintenance:​ While maintenance-free under normal conditions, periodic inspection of seals and guides is recommended in high-cycle applications.

8. Speed Control:​ Use flow control valves to adjust opening and closing speeds for smooth operation and to prevent workpiece damage.
