Compact New Pneumatic Cylinder FESTO 157217 AEVUZ-20-10-P-A For Industrial Control Applications

The FESTO AEVUZ-20-10-P-A, Order Number 157217, is a compact pneumatic cylinder from FESTO’s ADVU / AEVU family. It is a single-acting, pulling cylinder with a 20 mm piston diameter and a 10 mm stroke, designed for applications where installation space is limited but reliable linear motion is still required. FESTO’s family documentation also places the AEVU / AEVUZ range among compact cylinders that can save substantial installation space compared with larger ISO 15552-based cylinders, which is one of the reasons this product line remains useful in machine-building and automation work.

For this exact configuration, the official type code is important because it describes the mechanical version very clearly. In AEVUZ-20-10-P-A, the “Z” indicates the pulling version, the piston diameter is 20 mm, the stroke is 10 mm, “P” indicates elastic cushioning rings/plates at both ends, and the “A” version identifies the female-thread piston rod end. FESTO’s current family catalog lists 157217 specifically against AEVUZ-20-10-P-A, so this is a precise, orderable configuration rather than only a generic family reference.

Overview

The AEVUZ-20-10-P-A is built for compact, short-stroke actuation in industrial pneumatic systems. Its short 10 mm travel makes it suitable for tasks such as stopping, separating, clamping assistance, ejecting, or triggering mechanical functions in automation equipment. Because the cylinder is single-acting and pulling, it is best understood as a compact actuator for controlled return-oriented motion rather than as a long-travel transport cylinder. That gives it a different role from larger double-acting profile cylinders: it is meant for efficient, space-saving function actuation inside dense machine layouts.

From an engineering standpoint, the model offers a useful balance of compact size, dependable force, and simple integration. FESTO specifies position detection via proximity switch, optional mounting position, M5 piston rod thread, and an M5 pneumatic connection, all of which make the cylinder straightforward to integrate into compact machine modules and fixture designs. In practical use, this means the cylinder can be used not just as a simple pneumatic pusher, but as a monitored actuator that fits into PLC-controlled sequences and sensor-based automation logic.

Key Technical Specifications

All specifications above are based on FESTO’s official datasheet for Order Number 157217 and the current family catalog for the AEVU / AEVUZ range. The product weight for the 10 mm version is best stated as approximately 172 g, calculated from FESTO’s official 149 g base weight plus 23 g additional weight per 10 mm stroke.

Product Weight

Because you asked specifically for product weight, this point should be stated carefully and accurately. FESTO’s current datasheet does not print one final single-line total weight for this exact 10 mm version in the snippet returned by search, but it does provide the official weight basis: 149 g basic weight for 0 mm stroke and 23 g additional weight per 10 mm stroke. Based on that official method, the AEVUZ-20-10-P-A weighs approximately 172 g. That is the most defensible product-weight figure because it comes directly from FESTO’s own weight table rather than from reseller shipping data.

This distinction matters in industrial documentation. Some distributors list slightly higher logistical or shipping weights, typically around 174 g to 175 g, but those figures can include packaging or commercial handling tolerances. For technical product writing, the better value is the weight derived from FESTO’s official product data. If the cylinder is being used in a bill of materials, technical datasheet, or structured product catalog, approx. 172 g is the cleaner specification to use.

Design and Construction

The AEVUZ-20-10-P-A uses a compact piston-and-piston-rod design optimized for small installation spaces. FESTO describes it as a compact cylinder, and the broader family is promoted for applications where the user wants to save mounting space compared with larger standardized cylinders. This is commercially important because many real automation assemblies do not have room for full-profile cylinders, especially in fixtures, small transfer stations, compact packaging modules, or multi-axis handling setups.

The cylinder also includes elastic cushioning rings or plates at both ends, which helps absorb impact energy at the end positions. For a short-stroke compact cylinder, this is a practical advantage because it reduces end-of-stroke shock, helps protect the surrounding mechanism, and can improve repeatability in repetitive machine cycles. FESTO specifies an impact energy at end positions of 0.14 J, which is appropriate for this size class and indicates the intended operating envelope of the cylinder.

Another useful design feature is the female-thread piston rod end. In many machine designs, an internal thread gives more flexibility for adapters, couplings, and custom mechanical linkages than a fixed external stud. That can simplify mounting and alignment, especially when the actuator is integrated into a confined assembly where external thread projection would complicate the layout. Combined with the compact body dimensions, this makes the AEVUZ-20-10-P-A a practical option for engineers who want a clean and compact mechanical interface.

Performance and Functional Value

At 6 bar, FESTO specifies a theoretical advance force of 123 N, which places this cylinder in a useful range for compact industrial functions. That force level is not intended for heavy-duty pressing or long-travel load movement, but it is more than adequate for many short-stroke automation tasks such as part separation, stop functions, light clamping support, ejecting components, or actuating small mechanisms. In other words, the AEVUZ-20-10-P-A is designed for controlled compact motion, not for oversized force output.

The operating pressure range of 1 to 10 bar also gives the product practical flexibility across standard industrial compressed-air systems. FESTO additionally specifies compressed air according to ISO 8573-1:2010 [7:4:4], which confirms that the product is intended for normal industrial pneumatic service rather than exotic media. The note that lubricated operation is possible, but must then continue once chosen, is also an important maintenance detail because inconsistent lubrication practices can affect long-term sealing performance.

The official ambient temperature range of -20 °C to 80 °C, CRC 2 corrosion resistance, and PWIS conformity also indicate a product built for real factory environments. These specifications do not make the cylinder a special harsh-environment actuator, but they do show that it is intended for ordinary industrial service with moderate corrosion exposure and practical material compatibility requirements.

Materials and Durability

FESTO’s technical data indicate that the AEVUZ-20-10-P-A uses wrought aluminium alloy for the cover and cylinder barrel, high-alloy stainless steel for the piston rod, and NBR / TPE-U(PU) for the dynamic seals. This is a sensible material package for a compact industrial cylinder. Aluminium alloy keeps the actuator light and easy to integrate, while the stainless-steel piston rod supports durability and wear resistance in repetitive operation. The seal materials are typical for pneumatic service and suited to normal industrial compressed-air applications.

For users, that material combination translates into practical durability without unnecessary bulk. This is especially relevant in compact machines, where low component weight, good corrosion behavior, and predictable service life all matter. The relatively low product weight of about 172 g reinforces the product’s role as a compact industrial actuator rather than a heavy mechanical cylinder.

Typical Application Areas

These application examples are grounded in the cylinder’s official operating mode, stroke, force, pressure range, and sensing capability rather than in generic advertising language.

Conclusion

The FESTO AEVUZ-20-10-P-A, Order Number 157217, is a compact single-acting, pulling pneumatic cylinder designed for short-stroke industrial motion in space-constrained automation systems. Its official specification includes a 20 mm piston diameter, 10 mm stroke, M5 piston rod thread, female-thread rod end, elastic cushioning at both ends, proximity-switch position detection, 1 to 10 bar operating pressure, and a theoretical 123 N advance force at 6 bar. Based on FESTO’s official weight data, the product weight for this 10 mm configuration is approximately 172 g.

For users who need a compact, clearly specified, and technically practical pneumatic actuator, the AEVUZ-20-10-P-A is a strong option.
