VGFZ55-100-S Pneumatic Gripper with Shortened Stroke

Description VGFZ55-100-S

VGFZ55-100-S is a centering pneumatic gripper with a shortened stroke for applications where it is important not only to hold the part, but also to accurately fix it relative to the axis. The S designation in the model indicates a shortened stroke, which makes the gripper suitable for operations requiring compact jaw opening, high positioning accuracy, and reliable workpiece holding in an automated cycle. The model is used in robotic systems, automated lines, equipment loading systems, and production areas where the workpiece must be stably fed into a chuck, tooling, or technological position. The gripper has a stroke of 4 mm per jaw, an opening force of 396×P N, and a closing force of 344×P N. The maximum workpiece weight is 8 kg, while the gripper itself weighs 0.8 kg. Thanks to the combination of high force, low weight, and shortened stroke, the VGFZ55-100-S can be used where centering accuracy, cycle stability, and minimal extra load on the robotic unit are important.

Where the VGFZ55-100-S Is Used

The VGFZ55-100-S pneumatic gripper is relevant for production facilities where a robot or automatic mechanism works with parts that require precise centering. First of all, these include round, cylindrical, and symmetrical workpieces: bushings, rings, small housings, tube elements, and parts after machining. The model is especially suitable when the application requires:

• precise centering of the part relative to the axis;
• reliable holding of workpieces weighing up to 8 kg;
• operation as part of a robotic line;
• feeding a part into a machine, chuck, or tooling;
• cycle stability without manual adjustment.

The VGFZ55-100-S should not be selected based only on the maximum workpiece weight. We recommend considering the part shape, contact point, surface condition, transfer speed, and installation accuracy requirements. For example, a round part and a flat workpiece of the same weight will require different holding schemes: for cylindrical products, a centering gripper often provides a more stable result. To compare this model with other options by gripper type, force, and jaw stroke, you can go to the pneumatic grippers section.

What to Consider When Selecting a Gripper

The VGFZ55-100-S belongs to centering pneumatic grippers. Unlike conventional parallel models, this design helps hold the part evenly and position it more accurately relative to the central axis. This is especially important when automatically feeding parts into equipment, where even a slight offset can affect the quality of the cycle. Before choosing this model, it is worth checking:

• whether the 4 mm stroke per jaw is sufficient for your part;
• whether the closing force is suitable for the weight, shape, and surface of the workpiece;
• whether centering is required, rather than holding only;
• whether the center of gravity shifts during transfer;
• whether oil, chips, dust, or vibration are present in the working area;
• whether jaw position monitoring with sensors is required.

If the part enters the gripping area with slight deviations, it is worth additionally evaluating compensation modules, position monitoring sensors, and the shape of the working jaws. This approach helps reduce the load on the tooling, improve positioning accuracy, and make the robotic system more stable.

Design Features of the VGFZ55-100-S

The VGFZ55-100-S is designed for operation with high loads and precise part centering. The body is made of high-quality aircraft-grade aluminum, which makes it possible to combine strength, high load capacity, and minimal gripper weight. The design uses a three-tooth guide. Compared to a standard T-slot guide, it offers higher load-bearing capacity and a longer service life. This is especially important for automated lines where the gripper operates regularly, and stable part positioning affects the quality of the entire production cycle. The shortened stroke makes the model convenient for applications where a large opening is not required, but high accuracy, rigid fixation, and repeatable workpiece positioning are important.

Why It Is Better to Buy the VGFZ55-100-S Pneumatic Gripper from KIPVALVE

The VGFZ55-100-S is a solution for production facilities where precise centering, reliable holding, and correct operation in an automated cycle are important. For the gripper to operate reliably, its characteristics must be matched with actual operating conditions: the weight and geometry of the part, line speed, working pressure, transfer trajectory, and accuracy requirements. KIPVALVE helps select FOUK KIPVALVE pneumatic grippers for the tasks of industrial enterprises. We can assess whether the VGFZ55-100-S 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, centering type, or operating conditions.
