Application and Performance Profile
The Festo DSBC-100-320-D3-PPSA-N3 is a double-acting pneumatic cylinder engineered for linear motion tasks that demand both force and precision. With a 100 mm piston diameter and a 320 mm stroke, this unit delivers theoretical forces of 4712 N advancing and 4418 N retracting at 6 bar, making it suitable for medium-to-heavy pushing, lifting, or clamping operations. Its self-adjusting pneumatic end-position cushioning absorbs kinetic energy at stroke ends—rated at 2.5 J impact energy—which helps reduce mechanical shock and noise in cyclic applications. The cylinder conforms to ISO 15552, ensuring dimensional interchangeability with other standard cylinders, which simplifies integration into existing machine designs.
Design and Construction Details
The cylinder features a profile barrel made of smooth-anodized wrought aluminum alloy, with die-cast aluminum covers that are coated for corrosion resistance. The piston rod is high-alloy steel with an external M20x1.5 thread, and the rod wiper is TPE-E, while piston and buffer seals are TPE-U (PU). These material choices contribute to durability in environments with moderate corrosion stress (CRC 2). The unit is RoHS-compliant and conforms to VDMA24364-B1/B2-L for LABS (PWIS) compatibility, which is critical for paint and adhesive applications where silicone contamination must be avoided. The operating medium is compressed air per ISO 8573-1:2010 [7:4:4], and oil lubrication is permissible if required for downstream processes.
Mounting and Integration Flexibility
One of the key advantages of the DSBC series is its versatile mounting options. The DSBC-100-320-D3-PPSA-N3 can be mounted in any position, either via internal threads or using accessories, allowing engineers to orient the cylinder to suit the machine layout. The pneumatic connection is G1/2, and the cylinder is prepared for proximity sensor mounting, enabling position sensing without additional machining. The modular product system allows customization of cushioning, sensing, and corrosion protection, but this specific variant comes with self-adjusting cushioning and is designed for sensor attachment. This flexibility reduces design constraints and simplifies retrofitting into existing lines.
Operational Parameters and Environmental Limits
The cylinder operates within a pressure range of 0.4 to 12 bar, providing a wide window for force adjustment. Its ambient temperature tolerance spans from -20°C to 80°C, making it suitable for both cold storage areas and warm production floors. The cushioning length is 31 mm, which helps in fine-tuning deceleration for delicate loads. The moving mass at zero stroke is 1000 g, with an additional 39 g per 10 mm of stroke, while the basic weight is 3728 g plus 152 g per 10 mm stroke. These values are essential for calculating dynamic loads and selecting appropriate guiding and support structures.
Selection Considerations for Engineers and Buyers
When specifying this cylinder, consider the required force, stroke length, and mounting constraints. The 100 mm bore provides high force output, but also demands adequate air supply and flow rates—verify that your system can deliver the necessary volume at the required cycle rate. The self-adjusting cushioning reduces setup time, as it automatically adapts to load and speed changes, but for extremely high-speed applications, external shock absorbers may still be needed. The CRC 2 rating indicates suitability for typical industrial environments, but for harsh chemical or salt-laden atmospheres, a higher corrosion protection variant should be selected. Finally, the cylinder's weight and moving mass should be factored into the overall machine dynamics to avoid resonance or excessive stress on guides.
