VGFR57-151 Pneumatic Gripper for Parts up to 6.5 kg

Description VGFR57-151

VGFR57-151 is a parallel pneumatic gripper for automated production processes where stable holding of medium-weight and heavy parts is essential. The model is suitable for robotic lines, automatic machine loading, transfer of metal workpieces, housing components, and parts after machining. The gripper has a stroke of 13 mm per jaw, an opening force of 214×P N, and a closing force of 198×P N. The maximum workpiece weight is 6.5 kg, while the gripper itself weighs 1.45 kg. Thanks to these parameters, the VGFR57-151 can be used in applications where confident part fixation is required during transfer, feeding into equipment, or operation as part of an automated cell. The VGFR series is designed for use in various industrial sectors and can be applied in tasks where dust protection, high load capacity, centering accuracy, and stable operation within the production cycle are important. The body is made of high-quality aircraft-grade aluminum, so the gripper combines strength, load-bearing capacity, and moderate weight.

Where the VGFR57-151 Is Used

The VGFR57-151 pneumatic gripper is used in areas where a robot or automatic mechanism works with workpieces that require stable holding and cycle repeatability. The model is well suited for processes where it is important to reduce the risk of part displacement and maintain transfer accuracy. The VGFR57-151 is relevant for:

• automatic loading and unloading of machines;
• transferring metal workpieces weighing up to 6.5 kg;
• working with housing parts and tooling elements;
• robotic systems with a regular operating cycle;
• feeding parts into a technological position.

When selecting the VGFR57-151, it is important to consider not only the weight of the workpiece. A part weighing 6 kg may behave differently depending on its shape, length, center of gravity, and surface condition. If the workpiece is elongated, oily, or moved at high speed, the load on the jaws increases, and this should be taken into account at the selection stage. If the workpiece is a round bar and requires horizontal transfer, we recommend additionally evaluating the holding scheme, finger shape, and permissible moments. In some applications, two-finger parallel solutions from the FR series can provide more stable gripping when the tooling is selected correctly.

What to Consider When Selecting a Gripper

The VGFR57-151 belongs to parallel pneumatic grippers. The jaws move in parallel, which makes the model suitable for parts with flat, straight, or technologically convenient surfaces for fixation. This type of gripper is especially in demand in automation, where it is necessary to repeatedly pick and transfer similar workpieces. When selecting this model, we recommend considering not only the gripping force but also the permissible moments. If long fingers are used or the part has an offset center of gravity, the load on the guides may be higher than it appears based on the workpiece weight alone. For precision operations, it is also important to pay attention to repeatability, tooling quality, and jaw position monitoring. Before choosing this model, it is worth checking:

• whether the 13 mm stroke per jaw is sufficient for your part;
• whether the closing force is suitable for the actual weight and shape of the workpiece;
• whether the center of gravity is shifted during transfer;
• whether oil, chips, dust, or vibration are present in the working area;
• whether jaw position monitoring with sensors is required;
• whether misalignment compensation is needed when placing the part.

If the workpiece enters the gripping area with a slight deviation, we recommend additionally evaluating position monitoring sensors, compensation modules, and the shape of the working jaws. This helps improve cycle stability and reduce the load on the gripper, tooling, and robotic system.

Design Features of the VGFR57-151

The VGFR series design uses strong materials and wear-resistant treatment of working surfaces. This is important for production facilities where the gripper operates regularly, and line downtime due to unstable part holding is unacceptable. The gripper combines high load capacity and centering accuracy. If necessary, it can be used as part of systems that include position sensors, dust-protected versions, or additional components for demanding operating conditions.
