Core Specifications and Design
The Festo DSBC-80-500-D3-PPSA-N3 is a double-acting pneumatic cylinder with a piston diameter of 80 mm and a stroke of 500 mm. It conforms to ISO 15552, ensuring dimensional interchangeability with other cylinders built to the same standard. The cylinder features a profile barrel design with piston and piston rod, and the rod end is an external thread (M20x1.5). The pneumatic connection is G3/8. This model includes self-adjusting pneumatic end-position cushioning, which automatically adapts to load and speed changes, reducing impact and noise without manual adjustment. The cushioning length is 31 mm, and the impact energy in the end positions is rated at 1.8 J.
Position sensing is provided via slots on three sides, allowing contactless detection with proximity sensors. This enables reliable end-position and intermediate-position feedback for automation control. The cylinder can be mounted in any orientation, with options for internal threads or accessories, offering flexibility in machine design.
Performance and Operating Parameters
The DSBC-80-500-D3-PPSA-N3 operates with compressed air per ISO 8573-1:2010 [7:4:4] and can run with or without oil lubrication (though oil lubrication is required for further use). The operating pressure range is 0.4 to 12 bar. At 6 bar, the theoretical force is 3016 N advancing and 2721 N retracting. This force level suits medium to heavy loads and high-speed applications. The ambient temperature range is -20°C to 80°C, and the corrosion resistance class is 2, meaning it can withstand moderate corrosion stress—appropriate for typical industrial environments without aggressive chemicals.
The moving mass at 0 mm stroke is 810 g, with an additional 39 g per 10 mm of stroke. The basic weight is 2720 g, plus 143 g per 10 mm stroke. These values are useful for calculating dynamic loads and selecting appropriate guides or supports in high-cycle applications.
Materials and Compliance
Material selection contributes to durability and application suitability. The cylinder barrel and piston are made of wrought aluminum alloy, with the barrel smooth-anodized for wear resistance. The piston rod is high-alloy steel, and the cover is die-cast aluminum coated. Seals and wipers use TPE-U (PU) and TPE-E, while the cushion piston is POM. Bearing material is a metal-polymer compound, and nuts and flange screws are galvanized steel. The cylinder is RoHS-compliant and meets LABS (PWIS) conformity VDMA24364-B1/B2-L, making it suitable for use in paint shops and other applications requiring freedom from silicone and other wetting agents.
Integration and Installation Considerations
For engineers and procurement teams, the DSBC-80-500-D3-PPSA-N3 offers straightforward integration. Its ISO 15552 compliance simplifies mounting and replacement, and the sensor slots allow easy attachment of proximity switches without additional brackets. The self-adjusting cushioning reduces setup time, as there is no need to tune cushioning screws for different loads or speeds. The cylinder's any-position mounting and optional accessories (such as flange or foot mounts) provide design latitude.
When specifying, consider the operating pressure and force requirements, as well as the ambient temperature and corrosion exposure. The cylinder's theoretical forces at 6 bar are indicative; actual force will vary with supply pressure. Also, note the moving mass and weight to ensure adequate support and to calculate acceleration and deceleration forces in high-speed applications.
Practical Value in Automation
This Festo cylinder is a practical choice for applications such as material handling, packaging, and general machine automation where reliable linear motion is required. Its robust construction and self-adjusting cushioning help extend service life and reduce maintenance. The availability of position sensing supports precise control and diagnostics. For buyers, the ISO 15552 standard ensures a competitive sourcing environment, while the specific model number (8165598) ensures exact replacement or expansion consistency.
