Design and Construction
The Festo DSBC-100-250-D3-PPSA-N3 is a double-acting pneumatic cylinder built to ISO 15552, ensuring dimensional interchangeability with other standard cylinders. Its 100 mm piston diameter and 250 mm stroke make it suitable for medium-to-heavy linear actuation tasks. The cylinder features a profile barrel made of smooth-anodized wrought aluminum alloy, with die-cast aluminum coated covers. The piston rod is high-alloy steel with an external thread (M20x1.5), and the piston itself is wrought aluminum alloy. Seals and wipers are primarily TPE-U (PU), with a rod wiper of TPE-E and a cushion piston of POM. The bearing uses a metal-polymer compound, and fasteners are galvanized steel. All materials are RoHS-compliant.
The cylinder is designed for position sensing via proximity sensors, and its mounting position is unrestricted—any orientation is acceptable. It can be mounted using internal threads or with accessories, offering flexibility in integration.
Performance and Cushioning
Self-adjusting pneumatic end-position cushioning is a key feature, automatically adapting to load and speed changes. This reduces impact energy (rated at 2.5 J in end positions) and extends service life by minimizing mechanical stress. The cushioning length is 31 mm, providing controlled deceleration.
At 6 bar, the theoretical advancing force is 4712 N, and retracting force is 4418 N. Operating pressure range is 0.4 to 12 bar, and the cylinder can work with compressed air per ISO 8573-1:2010 [7:4:4]. Oil lubrication is possible if needed for downstream processes.
Ambient temperature range is -20°C to 80°C, and the corrosion resistance class is 2 (moderate corrosion stress), making it suitable for typical industrial environments without aggressive chemicals.
Integration and Accessories
As part of the Festo Core Range, this cylinder is complemented by a wide selection of mounting accessories and proximity sensors. The pneumatic connection is G1/2, a common port size that simplifies piping. The cylinder's profile barrel design allows for easy sensor attachment along its length, enabling reliable end-position detection.
Weight considerations are important for moving applications: basic weight with 0 mm stroke is 3728 g, with an additional 152 g per 10 mm stroke. Moving mass at 0 mm stroke is 1000 g, plus 39 g per 10 mm stroke. These values help engineers calculate dynamic loads and select appropriate guides or supports.
Application Considerations
Given its force output and stroke, the DSBC-100-250-D3-PPSA-N3 is well suited for clamping, pressing, lifting, or transferring operations in automation systems. Its ISO 15552 compliance ensures drop-in replacement in existing designs. The self-adjusting cushioning simplifies setup, as no manual cushioning adjustment is required, reducing commissioning time.
For applications with moderate corrosion risk (e.g., machining areas with coolant mist), the CRC 2 rating provides adequate protection. The LABS conformity (VDMA24364-B1/B2-L) indicates low paint-wetting impairment, which is beneficial in painting or coating lines.
When integrating, verify that the operating pressure and force meet the application's requirements. The theoretical forces are at 6 bar; actual force will vary with supply pressure. Also consider the moving mass and weight to ensure proper sizing of guiding and braking systems.
