VGTJL-70-250 Pneumatic Gripper for Heavy Workpieces

Description VGTJL-70-250

VGTJL-70-250 is a pneumatic two-finger parallel gripper with medium to high load capacity, designed for heavy-duty operating conditions. The model is intended for automated production tasks where it is necessary to reliably hold large and heavy parts, work with a wide opening range, and maintain stability during regular cycles.

The gripper is driven by two cylinders. The design uses a rack, synchronization mechanism, and linear guide bearing, which help ensure coordinated jaw movement and stable operation under load. This design is suitable for gripping hubs, massive workpieces, housing parts, tooling elements, and other products where standard compact solutions are no longer sufficient.

The VGTJL-70-250 has a stroke of 125 mm per jaw, an opening force of 4000 N, and a closing force of 4000 N. The maximum workpiece weight is 35 kg, while the gripper itself weighs 23 kg. These characteristics allow the model to be used in applications where a large stroke, high holding force, and reliable integration into a robotic or automated system are important.

Where the VGTJL-70-250 Is Used

The VGTJL-70-250 pneumatic gripper is used in production areas where a robot or automated mechanism handles heavy parts and must maintain stable holding during transfer, rotation, or placement of the workpiece into a technological position.

The VGTJL-70-250 is suitable for:

• automatic loading and unloading of equipment;
• transferring heavy workpieces weighing up to 35 kg;
• gripping hubs and other massive products;
• working with large housing parts and tooling elements;
• gripping parts with a large width or non-standard geometry;
• robotic lines with increased load on the gripper unit.

When selecting this model, it is important to consider not only the maximum workpiece weight. A part weighing 30–35 kg can create different loads depending on its length, shape, center of gravity, and robot movement speed. For example, a compact workpiece and a long part of the same weight will load the jaws, mounting system, and guides differently. Therefore, we recommend evaluating not just one characteristic, but the entire operating cycle.

If you need to compare the VGTJL-70-250 with other models by jaw stroke, force, and permissible workpiece weight, you can go to the pneumatic grippers section.

What to Consider When Selecting a Gripper

The VGTJL-70-250 is designed for applications requiring a large jaw stroke, high force, and stable operation with heavy parts. The 125 mm stroke per jaw allows the model to be used for workpieces that require a wide opening range during gripping or release.

Before choosing this model, it is worth checking:

• whether the 125 mm stroke per jaw is sufficient for your part;
• whether the 4000 N force is suitable for the weight, shape, and surface of the workpiece;
• whether the center of gravity of the part is offset relative to the gripping axis;
• whether the robotic system can withstand the total weight of the gripper and workpiece;
• whether vibration, chips, oil, or dust are present in the working area;
• whether misalignment compensation is needed when placing the part;
• whether the finger design is suitable for the shape of the specific product.

Special attention should be paid to the payload capacity of the robot or gantry system. The VGTJL-70-250 itself weighs 23 kg, so when making calculations, it is important to consider not only the workpiece weight, but also the weight of the gripper, mounting components, adapter plates, and additional tooling. This helps prevent equipment overload and maintain cycle stability.

If the workpiece enters the gripping area with slight deviations, we recommend evaluating compensation modules and position monitoring sensors in advance. This helps reduce the load on the tooling, improve positioning accuracy, and make the robotic system more stable.

Design Features of the VGTJL-70-250

The VGTJL-70-250 belongs to a series of grippers for heavy-duty operating conditions. Two cylinders drive the jaws, the rack helps synchronize movement, and the linear guide bearing increases mechanism stability when working with large parts.

This design is especially useful when gripping hubs, massive metal workpieces, and products with a large width. The gripper allows operation under high load and helps maintain a stable part position when moving between production operations.

To ensure reliable holding of a specific workpiece, it is important to properly design the working fingers. Their shape must match the part geometry, contact points, and transfer conditions. KIPVALVE helps evaluate not only the gripper itself, but also the tooling that affects the stability of the entire unit.

Why It Is Better to Buy the VGTJL-70-250 Pneumatic Gripper from KIPVALVE

The VGTJL-70-250 is a solution for production facilities where confident gripping of heavy parts, a large jaw stroke, and reliable operation in an automated system are required. For the equipment to work correctly, the model characteristics must be matched with actual operating conditions: the weight and geometry of the workpiece, transfer speed, working pressure, movement trajectory, and accuracy requirements.

KIPVALVE helps select FOUK KIPVALVE pneumatic grippers for the tasks of industrial enterprises. We can assess whether the VGTJL-70-250 is suitable for your part or offer another model from the series if a different option is required in terms of jaw stroke, force, workpiece weight, guide type, or operating conditions.
