Overview and Key Specifications
The Festo DSBC-100-250-D3-PPVA-N3 (manufacturer ID 8165654) is a double-acting pneumatic cylinder with a 100 mm piston diameter and a 250 mm stroke. It conforms to ISO 15552, ensuring interchangeability in standard mounting patterns. The cylinder is designed for position sensing via proximity sensors, with sensor slots on three profile sides for flexible integration. Its operating pressure range is 0.4 to 12 bar, and it can operate in any mounting position. The theoretical force at 6 bar is 4712 N advancing and 4418 N retracting, making it suitable for medium-to-heavy duty applications.
Construction and Materials
The DSBC-100-250-D3-PPVA-N3 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 is wrought aluminum alloy. Seals and wipers are primarily TPE-U (PU) and TPE-E, providing good wear resistance. The bearing uses a metal-polymer compound, and all fasteners are galvanized steel. The cylinder is RoHS-compliant and meets corrosion resistance class 2 (moderate corrosion stress) per Festo standard 940 070, making it suitable for typical industrial environments without aggressive chemicals.
Cushioning and Performance
This cylinder is equipped with pneumatic cushioning that is adjustable at both ends. The cushioning length is 31 mm, and the impact energy in the end positions is rated at 2.5 J. This adjustability allows engineers to fine-tune deceleration to reduce noise and mechanical stress, extending the life of the cylinder and the driven load. The moving mass at 0 mm stroke is 1000 g, with an additional 39 g per 10 mm stroke, while the basic weight is 3728 g plus 152 g per 10 mm stroke. These values are critical for calculating dynamic loads and selecting appropriate guide systems.
Integration and Mounting Flexibility
The DSBC-100-250-D3-PPVA-N3 offers versatile mounting options. It can be mounted using internal threads or with accessories, and it supports lateral valve mounting, which is particularly useful for decentralized valve placement in large systems. The cylinder has a G1/2 pneumatic connection, and its design allows for easy integration with proximity switches. The sensor slots on three sides simplify the addition of position feedback, enabling precise control and monitoring in automated processes. This flexibility reduces design effort and installation time.
Application Considerations
Given its force output and stroke, this cylinder is well-suited for applications such as clamping, pressing, lifting, and material handling in assembly lines, packaging machinery, and general automation. The operating medium is compressed air per ISO 8573-1:2010 [7:4:4], and oil lubrication is possible if required for downstream processes. The ambient temperature range is -20°C to 80°C, making it adaptable to various shop floor conditions. The cylinder also conforms to LABS (PWIS) VDMA24364-B1/B2-L, which is important for paint and coating environments. When selecting this cylinder, engineers should verify that the cushioning settings match the load and speed to avoid excessive impact, and consider the total moving mass to ensure proper sizing of guides and supports.
