Overview and Key Specifications
The Festo DSBC-100-25-D3-PPVA-N3 is a double-acting pneumatic cylinder with a 100 mm piston diameter and a 25 mm stroke. It is designed for industrial applications requiring precise linear motion and reliable operation. The cylinder conforms to ISO 15552, ensuring dimensional compatibility with a wide range of mounting accessories and system components. Its piston rod features an external M20x1.5 thread, and the pneumatic connection is G1/2. The unit operates within a pressure range of 0.4 to 12 bar and is suitable for ambient temperatures from -20°C to 80°C.
The cylinder is built with a profile barrel and die-cast aluminum covers, both coated for durability. The piston rod is made of high-alloy steel, and the piston itself is of wrought aluminum alloy. Seals and wipers are primarily TPE-U(PU) and TPE-E, chosen for wear resistance. The design includes a metal polymer compound bearing, contributing to smooth rod movement and long service life.
Performance and Cushioning
At a supply pressure of 6 bar, the theoretical force is 4712 N advancing and 4418 N retracting. This force output makes the cylinder suitable for medium-duty pushing, pulling, lifting, or clamping tasks. The cushioning is pneumatic and adjustable at both ends, allowing operators to fine-tune deceleration to reduce impact and noise. The cushioning length is 31 mm, and the impact energy in the end positions is rated at 2.5 J, which helps protect the cylinder and connected equipment from shock loads.
The moving mass at zero stroke is 1000 g, with an additional 39 g per 10 mm of stroke. The basic weight is 3728 g, plus 152 g per 10 mm stroke. These figures are useful for calculating dynamic loads and selecting appropriate guides or supports in high-speed applications.
Construction and Material Quality
Festo has specified materials that balance strength, weight, and corrosion resistance. The cylinder barrel is made of smooth-anodized wrought aluminum alloy, which provides a low-friction surface and good wear characteristics. The piston rod is high-alloy steel, offering high tensile strength and resistance to bending under side loads. The corrosion resistance class (CRC) is 2, meaning the cylinder can withstand moderate corrosion stress, such as in humid or mildly contaminated environments without aggressive chemicals.
All materials are RoHS-compliant, and the cylinder meets LABS (PWIS) conformity to VDMA24364-B1/B2-L, making it suitable for use in paint shops and other applications where silicone-free components are required. The nut and flange screws are galvanized steel, adding to the overall corrosion protection.
Integration and Mounting Flexibility
The DSBC-100-25-D3-PPVA-N3 can be mounted in any position, offering flexibility in machine design. It can be installed using internal threads or with a variety of accessories such as foot, flange, or trunnion mounts (not included). This versatility simplifies integration into existing automation systems, whether for new builds or retrofits.
The cylinder is equipped for proximity sensor mounting, enabling position sensing without mechanical contact. This is essential for applications requiring end-of-stroke detection or mid-stroke feedback. The piston rod end is an external thread, which is a common interface for attaching tooling or linkages.
Application Considerations
Given its 100 mm bore and 25 mm stroke, this cylinder is best suited for short-stroke, high-force operations. Typical uses include clamping fixtures, pressing operations, stamping dies, or as a positioning element in assembly lines. The adjustable cushioning is particularly valuable in high-cycle applications where smooth deceleration extends the life of the cylinder and reduces maintenance.
The operating medium is compressed air per ISO 8573-1:2010 [7:4:4], and oil lubrication is possible if needed for downstream components. The cylinder is double-acting, providing force in both directions, which is often required for controlled motion in automated processes. With its robust construction and adherence to ISO standards, this Festo cylinder is a dependable choice for engineers seeking a balance of performance and durability.
