VGTR20-51 pneumatic gripper for gripping and moving lightweight parts

Description VGTR20-51

The VGTR20-51 is a compact parallel pneumatic gripper from FOUK KIPVALVE, designed for precise gripping, holding, and handling of lightweight workpieces in automated production systems. The model is intended for use with industrial and collaborative robots, automatic lines, assembly stations, and equipment where small actuator footprint, high operating speed, and stable repeatability are critical.

The gripper features two parallel-moving jaws that provide reliable workpiece retention while maintaining high positioning accuracy. Its compact design makes it easy to integrate into robotic cells with limited space.

The VGTR20-51 offers a stroke per jaw of 4 mm, an opening force of 27×P N, and a closing force of 24×P N. The maximum permissible workpiece weight is 0.6 kg, while the gripper itself weighs only 0.15 kg. This combination of characteristics minimizes the load on the robotic manipulator and preserves high system dynamics.

Applications of the VGTR20-51 Pneumatic Gripper

The VGTR20-51 is used in manufacturing processes that require fast and precise transfer of small components between operations. The gripper is suitable for handling metal blanks, bushings, small housings, plastic parts, electronic components, and machined workpieces.

Typical applications include:

• Automated machine loading and unloading;
• Transfer of parts between production stations;
• Feeding workpieces into tooling and fixtures;
• Integration into robotic cells;
• Sorting and kitting operations;
• Assembly and packaging tasks.

VGTR series grippers are widely used in mechanical engineering, instrument making, metalworking, electronics, and other industries where high speed and production stability are essential.

Design Features of the VGTR20-51

The VGTR series comprises versatile parallel pneumatic grippers for industrial robots. The two moving jaws travel strictly parallel to each other, ensuring reliable workpiece retention and high positioning repeatability.

Custom fingers can be mounted on the jaws to suit the specific geometry, dimensions, and surface characteristics of the workpiece. This tailored approach enhances grip security and minimizes the risk of damage during transport.

The VGTR20-51 body is manufactured from high-grade aviation aluminum, combining low dead weight with excellent mechanical strength and resistance to operational stress.

The gripper incorporates wear-resistant guides and durable internal components, rated for millions of open-close cycles under intensive operating conditions.

Key Considerations for Selection

When choosing a pneumatic gripper, it is important to consider not only the workpiece weight but also the specific process requirements.

Before final selection, we recommend verifying the following:

• Is the 4 mm stroke per jaw sufficient for the workpiece?
• Does the gripping force meet the actual load requirements?
• Is the gripping point correctly chosen?
• Are there additional loads caused by the center of gravity offset?
• Are oil, chips, vibration, or other external factors present in the working environment?
• Is position sensing or jaw monitoring required?

Workpieces with identical weight can impose different loads on the gripper. For example, a compact bushing and a long, slender part weighing 0.5 kg will affect the jaws differently due to varying leverage.

If your application requires tolerance compensation, position verification, or handling of non-standard geometries, KIPVALVE specialists can assist in selecting additional components such as sensors, compensation modules, mounting hardware, and custom fingers.
