Core Specifications and Design
The Festo DSBC-100-500-D3-PPSA-N3 (manufacturer ID 8165687) is a double-acting pneumatic cylinder with a 100 mm piston diameter and a 500 mm stroke. It conforms to ISO 15552, ensuring dimensional interchangeability with other standard cylinders. The cylinder features a profile barrel design with a piston and piston rod, and the piston rod end is an external thread (M20x1.5). It is available with a piston rod at one end only.
This model includes self-adjusting pneumatic end-position cushioning, which automatically tunes the cushioning effect to the load and speed, reducing impact and wear. The cushioning length is 31 mm, and the impact energy in the end positions is rated at 2.5 J. The cylinder can be mounted in any position, and mounting options include internal threads or accessories, providing flexibility for various machine layouts.
Performance and Operating Parameters
The DSBC-100-500-D3-PPSA-N3 operates with compressed air per ISO 8573-1:2010 [7:4:4] and can run with or without oil lubrication (if oil is used initially, it must continue to be used). The operating pressure range is 0.4 to 12 bar. At 6 bar, the theoretical advancing force is 4712 N, and the retracting force is 4418 N, making it suitable for medium-to-heavy duty applications.
The cylinder is designed for a wide ambient temperature range from -20°C to 80°C. It has a corrosion resistance class (CRC) of 2, indicating moderate corrosion stress resistance, and it meets LABS (PWIS) conformity per VDMA24364-B1/B2-L, which is important for paint and adhesive applications.
Position Sensing and Control
This cylinder is equipped with sensor slots on three sides (feature D3), allowing for easy mounting of proximity sensors. This enables precise position sensing and control, which is essential for automation tasks requiring accurate end-position detection or mid-stroke sensing. The sensor slots are integrated into the profile barrel, simplifying installation and adjustment.
Materials and Construction
The DSBC-100-500-D3-PPSA-N3 is built with high-quality materials to ensure durability and long service life. The cylinder barrel is made of wrought aluminum alloy with a smooth-anodized finish, and the piston is also wrought aluminum alloy. The piston rod is high-alloy steel, and the cover material is die-cast aluminum with a coating. Seals are made of TPE-U(PU) for the piston, rod wiper, and buffer, while the cushion piston uses POM. The bearing is a metal polymer compound, and nuts and flange screws are galvanized steel. All materials are RoHS-compliant.
Weight and Integration Considerations
For integration into existing systems, it is helpful to know the weight characteristics. The basic weight with 0 mm stroke is 3728 g, with an additional 152 g per 10 mm of stroke. The moving mass at 0 mm stroke is 1000 g, plus 39 g per 10 mm of stroke. These values are important for calculating dynamic loads and selecting appropriate guides or supports.
The pneumatic connection is G1/2, which is a common port size for this cylinder class. The cylinder's design allows for versatile mounting, including through piston rod and female thread options, making it adaptable to various installation scenarios.
