New Standards-Based Pneumatic Cylinder FESTO 2102629 DSBC-50-30-PPSA-N3 Wonderful To Short-Travel Industrial Functions

Product Specification Table

All specifications in the table above are based on FESTO’s official product page, the dedicated datasheet for part number 2102629, and the current DSBC series catalog.

Product Overview

The FESTO DSBC-50-30-PPSA-N3, order number 2102629, is a standards-based pneumatic cylinder designed for reliable linear motion in industrial automation. It belongs to the DSBC family and is built in accordance with ISO 15552, which makes it suitable for machine builders and maintenance teams that prefer internationally standardized cylinder dimensions, mounting logic, and integration practices. The model combines a 50 mm bore with a 30 mm stroke, giving it a compact travel range while still delivering meaningful output force for short-stroke industrial tasks.

This cylinder is a double-acting design, which means compressed air is used for both extension and retraction. That operating principle is important in applications where the user needs controlled forward and return movement rather than a spring-return mechanism. FESTO also specifies position detection via proximity switch, allowing the actuator to be integrated into automated systems that require end-position monitoring, sequence control, or process confirmation. In practical machine design, that supports better feedback, more dependable timing, and easier diagnostics.

A Short-Stroke Cylinder with Practical Force

The DSBC-50-30-PPSA-N3 is especially relevant where the machine does not need long linear travel but still needs a solid and stable pneumatic push. With a theoretical force of 1178 N on the advance stroke and 990 N on the return stroke at 6 bar, this model sits in a useful range for clamping, pressing, stopping, ejecting, separating, or positioning components over a short distance. In production systems, that combination often matters more than long stroke length, because many industrial actions are localized and repeatable rather than extended.

A 30 mm stroke is short enough for compact fixtures and station modules, yet long enough to provide controlled displacement in assembly tools, packaging stations, pallet handling units, inspection devices, and material stops. The 50 mm bore gives the actuator a stronger force profile than smaller ISO cylinders, so it can be selected where a 32 mm or 40 mm cylinder may be too light for the load or the required holding margin. This makes the model attractive for users who want force density without moving to a much larger pneumatic footprint. That is an engineering inference based on the official bore, stroke, and force values.

What Makes the PPSA Version Different

One of the most important features of this exact model is the PPSA cushioning concept. In the DSBC series, FESTO distinguishes between several cushioning variants. The PPS version is defined in the official DSBC catalog as pneumatic cushioning, self-adjusting at both ends, while the dedicated datasheet for this exact cylinder describes it as self-adjusting pneumatic end-position cushioning. This is the key difference between this model and manually adjustable PPV versions.

From an application standpoint, self-adjusting cushioning is useful because it reduces the amount of manual tuning required during installation or commissioning. In many machines, the operating conditions are repetitive enough that a self-adjusting end-position behavior can simplify setup and reduce the need for repeated adjustment by maintenance staff. For OEM users and system integrators, that can translate into easier deployment, more consistent behavior across machines, and less time spent optimizing end-position damping manually. This is a practical engineering interpretation of FESTO’s official PPS cushioning description.

The cylinder’s cushioning length is 22 mm, and the impact energy in the end positions is listed as 1 J. Those values help frame the operating envelope of the product and show that FESTO has defined the end-of-stroke motion behavior in technical terms rather than leaving it as a generic cylinder feature. For short-stroke automation, that matters because end-position impact is often one of the main factors influencing noise, wear, and long-term stability.

Mechanical and Installation Characteristics

Mechanically, the FESTO 2102629 uses a male piston rod thread with size M16x1.5, and the pneumatic connection is G1/4. FESTO lists the mounting position as optional, and mounting can be carried out via female thread or with accessories. These details make the cylinder flexible in standard machine layouts, whether it is installed on a bracket, integrated into a frame, or paired with other FESTO-compatible mounting components.

The construction materials are also clearly stated in the official datasheet. FESTO specifies a coated die-cast aluminium cover, a smooth-anodised wrought aluminium alloy cylinder barrel, a high-alloy steel piston rod, and TPE-U (PU) sealing elements in the piston seal and piston rod wiper. The datasheet also notes RoHS compliance, which is relevant for many international industrial supply chains and documentation requirements.

For operating conditions, the cylinder is designed for compressed air to ISO 8573-1:2010 [7:4:4], with an operating pressure range of 0.04 MPa to 1.2 MPa, or 0.4 bar to 12 bar. FESTO further notes that lubricated operation is possible, but if lubrication is used, it must continue to be used. The specified ambient temperature range is -20 °C to 80 °C, and the product carries CRC 2 for moderate corrosion stress. The datasheet also lists LABS conformity and cleanroom suitability up to Class 5 according to ISO 14644-1, measured according to ISO 14644-14. These details show that the cylinder is not just a simple general-purpose actuator; it is a standardized industrial component with clearly documented operating boundaries.

Product Weight and Engineering Significance

The official product weight is 1358 g, which is an important specification for more than just shipping. In real machine construction, cylinder weight affects mounting strength, moving assembly calculations, transport packaging, and replacement planning. FESTO also gives a basic weight of 1190 g at 0 mm stroke and an additional weight of 56 g per 10 mm stroke. When applied to a 30 mm stroke, that calculation results in 1358 g, exactly matching the official product weight listed in the datasheet. That consistency is useful because it shows the number is structurally derived from the DSBC family data and not just a standalone catalog entry.

For users working on automated fixtures or moving modules, the datasheet also lists a moving mass of 440 g, with 365 g at 0 mm stroke and 25 g additional moving mass per 10 mm stroke. That gives engineers a better basis for motion-related calculations when considering acceleration, deceleration, and impact behavior at the end positions. In other words, the weight information here is unusually useful because FESTO separates total product weight from moving mass.

Suitable Industrial Uses

Based on its official specifications, the DSBC-50-30-PPSA-N3 is well suited to short-travel industrial functions that require a robust ISO cylinder with predictable end-position behavior. Typical uses can include part stopping, workpiece clamping, fixture actuation, transfer gate movement, push-off or eject functions, and short-range positioning tasks in assembly, packaging, material handling, or inspection equipment. These use cases are reasoned from the product’s bore, stroke, double-acting design, proximity-switch compatibility, ISO mounting standard, and self-adjusting cushioning characteristics.

This model is particularly attractive in situations where the user wants the benefits of a standardized FESTO cylinder but prefers self-adjusting cushioning over manual end-position tuning. That distinction can matter in production environments where installation speed, repeatability, and maintenance efficiency are more important than fine manual adjustment. For replacement projects, the ISO 15552 conformity also helps because it supports dimensional compatibility within standardized cylinder classes.

Why This Model Has Purchasing Value

From a purchasing and stock perspective, FESTO 2102629 DSBC-50-30-PPSA-N3 is a clear, traceable industrial part number tied to a well-documented actuator platform. Buyers are not selecting an undefined generic cylinder here. They are selecting a 50 mm bore, 30 mm stroke, double-acting, ISO 15552 cylinder with self-adjusting pneumatic cushioning, M16x1.5 rod thread, G1/4 connection, and an official weight of 1358 g. That level of specification makes quoting, substitution checking, maintenance stocking, and technical communication much easier.
