The FESTO 560206 HGPT-25-A-B-G2 is a heavy-duty parallel gripper developed for industrial automation systems that require stable gripping, high mechanical rigidity, and dependable part retention during handling cycles. As part of the HGPT series, this model is designed for applications in which the gripper must do more than simply open and close. It is intended for repeatable production environments where jaw guidance accuracy, resistance to mechanical load, and long service life are important for machine reliability. FESTO identifies this exact model as a size 25 pneumatic parallel gripper with 6 mm stroke per jaw, double-acting operation, and gripping force retention in the closing direction. The official FESTO datasheet also lists a product weight of 353 g.
In practical machine design, a parallel gripper is often one of the most critical end-effector components in the motion chain. It directly affects handling accuracy, cycle consistency, and part security during transfer. The HGPT-25-A-B-G2 is positioned for users who need a gripper that is compact but mechanically stronger than light-duty miniature types. FESTO describes the HGPT range as a heavy-duty gripper, and this specific version includes closing gripping force retention, meaning the gripper can help retain the workpiece in the closed state even when air pressure is no longer actively supporting the grip under defined conditions. That is a meaningful feature for automation engineers working on vertical handling, safety-oriented gripping logic, or process steps where temporary pressure loss must not immediately result in dropped parts.

Design Concept and Functional Role
The HGPT-25-A-B-G2 is designed for industrial gripping tasks that demand rigidity and repeatability. Unlike a light-duty handling gripper that may be suitable only for small, low-load operations, the HGPT design uses a wedge-drive mechanism with a forced guide motion sequence, according to FESTO’s datasheet. That construction approach is important because it supports better load distribution and stable jaw guidance, especially in repetitive automation cycles where parts are picked, transferred, positioned, and released at high frequency.
A major distinguishing feature of this model is the suffix G2, which FESTO’s HGPT documentation identifies as closing gripping force retention. In engineering terms, this means the gripper is configured so that force-retention support acts in the closing direction. FESTO explains that HGPT versions with integrated spring systems, including G2 models, can be used as single-acting grippers, as grippers with supplementary gripping force, or as grippers with gripping force retention, depending on the application. This makes the HGPT-25-A-B-G2 more versatile than a standard double-acting gripper without retention logic.
Technical Highlights
| Technical Feature | Practical Benefit |
|---|---|
| Heavy-duty parallel gripper design | Better suited for industrial handling loads |
| 6 mm stroke per jaw | Useful travel range for many standard gripping tasks |
| Closing gripping force retention | Helps secure parts in the closed position |
| Double-acting pneumatic operation | Predictable opening and closing control |
| Repeat accuracy 0.04 mm | Supports consistent positioning in automation |
| Maximum operating frequency 3 Hz | Suitable for repetitive machine cycles |
| M5 pneumatic ports | Standard compact pneumatic connection |
| 353 g product weight | Good balance of rigidity and manageable size |
These features are directly supported by FESTO’s official product datasheet and series documentation.
Weight and Mechanical Integration
The product weight of the FESTO HGPT-25-A-B-G2 is 353 g. That figure is important in actual machine development because gripper weight affects the payload budget of the axis carrying it, the dynamic response of robotic or linear handling units, and the overall mechanical stiffness of the end-of-arm system. A 353 g gripper is not ultra-light, but that is consistent with its heavy-duty purpose. The weight reflects a design intended to provide more structural stability and gripping security than miniature grippers that prioritize only low mass.
For integrators, the weight also matters when selecting mounting brackets and sizing actuator payloads. FESTO states that the HGPT-25-A-B-G2 can be mounted via female thread and centring sleeve, through-hole and centring sleeve, through-hole and dowel pin, or female thread and dowel pin, depending on the mounting concept used. That flexibility is useful in machine design because it allows the gripper to be installed in ways that prioritize either quick assembly, precision alignment, or resistance to torsional load.
Accuracy, Speed, and Jaw Performance
In automated handling, gripping accuracy is as important as gripping force. FESTO lists a repeat accuracy of 0.04 mm for this model, along with a maximum replacement accuracy of 0.2 mm. These values indicate that the gripper is intended for repeatable positioning tasks in industrial assembly and part-transfer systems, not merely rough material handling. The datasheet also specifies maximum jaw play Sz of 0.02 mm and maximum angular jaw clearance ax, ay of 0.1 degrees, which further supports the view that this gripper is built for controlled and stable jaw motion.
Speed-related data is also relevant. FESTO specifies a minimum opening time of 40 ms and minimum closing time of 28 ms at 6 bar, as well as a maximum operating frequency of 3 Hz. These figures show that the HGPT-25-A-B-G2 is suitable for repetitive production equipment while remaining within a mechanically robust operating envelope. It is not marketed as an ultra-high-speed microgripper. Instead, it is positioned as a more durable and controlled gripping solution for demanding automation use.
Typical Application Areas
| Application Area | Why This Gripper Fits |
|---|---|
| Assembly automation | Good repeatability and controlled jaw guidance |
| Machine loading and unloading | Heavy-duty structure supports regular cycle work |
| Pick-and-place systems | Parallel jaw motion suits standard workpiece handling |
| Vertical handling tasks | Closing retention feature can improve part security |
| End-of-arm tooling | Balanced size and weight for industrial integration |
These application examples are inferred from the gripper’s official heavy-duty classification, repeatability data, and G2 retention configuration.
Materials and Service Considerations
FESTO states that the HGPT-25-A-B-G2 is RoHS-compliant, and the current datasheet lists anodised aluminium for the housing and high-alloy stainless steel for the cover cap. These material choices are typical for industrial automation components where low weight, corrosion resistance, and mechanical durability must be balanced. The datasheet also notes a relubrication interval for guidance elements of 5 million cycles, which is a useful maintenance figure for engineers planning service intervals in continuous-production environments.
From a pneumatic perspective, the gripper operates with compressed air according to ISO 8573-1:2010 [7:4:4], and FESTO notes that lubricated operation is permitted, but once lubricated air is used, the product should continue to be operated with lubricated air. That is an important practical point because inconsistent lubrication practice can shorten seal life or affect long-term motion behavior.
Why Buyers Choose This Model
For procurement teams and maintenance departments, the HGPT-25-A-B-G2 is attractive because it combines several useful characteristics in one defined part number: heavy-duty design, parallel gripper function, size 25 format, 6 mm jaw stroke, and closing gripping force retention. Those are not interchangeable details. In gripper selection, a mismatch in size, retention logic, or stroke can make the replacement unusable even if it appears visually similar. The full identifier 560206 / HGPT-25-A-B-G2 therefore matters for accurate purchasing.
Conclusion
The FESTO 560206 HGPT-25-A-B-G2 is a robust heavy-duty pneumatic parallel gripper built for industrial handling tasks that require stable jaw guidance, repeatable motion, and additional security in the closed gripping direction. Official FESTO data confirms that this model offers 6 mm stroke per jaw, double-acting operation, closing gripping force retention, 4 to 8 bar working pressure, repeat accuracy of 0.04 mm, M5 pneumatic connection, and a product weight of 353 g. Taken together, these characteristics make it a strong choice for assembly automation, machine loading, pick-and-place systems, and other demanding gripping applications where mechanical reliability matters as much as speed.
