Overview and Core Specifications
The Festo DSBC-80-400-D3-PPVA-N3 is a double-acting pneumatic cylinder designed for medium to heavy load applications. With an 80 mm piston diameter and a 400 mm stroke, this ISO 15552-compliant unit delivers reliable linear motion in a compact profile barrel design. The cylinder operates within a pressure range of 0.4 to 12 bar and is suitable for ambient temperatures from -20°C to 80°C. Its theoretical force output at 6 bar is 3016 N advancing and 2721 N retracting, making it a robust choice for demanding industrial tasks.
Construction and Materials
The DSBC-80-400-D3-PPVA-N3 features a high-alloy steel piston rod with an external M20x1.5 thread, ensuring excellent running performance and long service life. The cylinder barrel is made of smooth-anodized wrought aluminum alloy, contributing to low overall weight while maintaining structural integrity. Covers are die-cast aluminum with a protective coating, and seals are primarily TPE-U(PU) for durability. The piston itself is wrought aluminum alloy, and the bearing uses a metal-polymer compound for reduced friction. All materials are RoHS-compliant, and the unit meets corrosion resistance class 2, suitable for moderate corrosion stress.
Performance and Cushioning
Adjustable pneumatic cushioning at both ends absorbs impact energy up to 1.8 J, with a cushioning length of 31 mm. This feature minimizes noise and vibration at end positions, protecting the cylinder and connected equipment. The moving mass at zero stroke is 810 g, with an additional 39 g per 10 mm of stroke, while the basic weight is 2720 g plus 143 g per 10 mm stroke. These values are critical for calculating dynamic loads and selecting appropriate mounting accessories.
Integration and Sensing
The cylinder is designed for flexible mounting in any position, with options for internal threads or accessories. It includes sensor slots on three sides, enabling contactless position sensing via proximity sensors. This supports precise monitoring and control of piston rod position, which is essential for automated sequences. The pneumatic connection is G3/8, and the unit operates with compressed air per ISO 8573-1:2010 [7:4:4]. Oil lubrication is possible if required for further use, and the product conforms to VDMA24364-B1/B2-L for LABS (PWIS) compatibility.
Application Considerations
When integrating the DSBC-80-400-D3-PPVA-N3, engineers should account for its theoretical forces and cushioning characteristics. The cylinder is well-suited for applications such as material handling, clamping, and general automation where reliable, repeatable motion is needed. Its ISO 15552 compliance ensures interchangeability with other standard cylinders, simplifying replacement or system expansion. For procurement teams, the unit's robust construction and adjustable cushioning offer long-term value in high-cycle environments. Always verify that the operating pressure, temperature range, and media quality match your system requirements to optimize performance and service life.
