Overview and Key Specifications
The Festo DSBC-100-125-D3-PPVA-N3 (manufacturer ID 8165650) is a double-acting pneumatic cylinder engineered for demanding automation tasks. With a 100 mm piston diameter and 125 mm stroke, this ISO 15552-compliant unit delivers a theoretical force of 4712 N advancing and 4418 N retracting at 6 bar. Its robust design includes a profile barrel and die-cast aluminum covers, with a high-alloy steel piston rod featuring an M20x1.5 external thread. 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, making it adaptable to various industrial environments.
Performance and Cushioning
The DSBC-100-125-D3-PPVA-N3 is built for precise, controlled motion. Its adjustable pneumatic cushioning at both ends absorbs impact energy up to 2.5 J, with a cushioning length of 31 mm. This feature reduces end-position shock, prolonging component life and minimizing noise. The cylinder's moving mass at 0 mm 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 parameters allow engineers to calculate dynamic loads accurately for high-cycle applications.
Construction and Materials
Material selection reflects a balance of durability and weight. The cylinder barrel is made of smooth-anodized wrought aluminum alloy, while the piston uses the same alloy for lightweight strength. The piston rod is high-alloy steel, and seals are TPE-U(PU) for the piston, rod wiper, and buffer, with a TPE-E rod wiper. The cushion piston is POM, and bearings use a metal-polymer compound. All materials are RoHS-compliant, and the unit meets LABS (PWIS) conformity to VDMA24364-B1/B2-L, ensuring compatibility in paint and adhesive applications.
Mounting and Integration
Flexibility in mounting is a key advantage. The cylinder can be mounted using internal threads or via accessories, and its mounting position is unrestricted (any orientation). It features a G1/2 pneumatic connection and is prepared for proximity sensors, enabling position sensing without additional machining. Conformance to ISO 15552 ensures interchangeability with other standard cylinders, simplifying system design and retrofits. The corrosion resistance class (CRC 2) indicates moderate corrosion resistance, suitable for typical factory floors but not aggressive chemical exposure.
Application Considerations
This cylinder is well-suited for material handling, packaging, and general automation where reliable force and stroke are required. The double-acting mode provides controlled extension and retraction, while the adjustable cushioning allows fine-tuning for varying loads. Operating medium is compressed air per ISO 8573-1:2010 [7:4:4], and oil lubrication is possible if needed for downstream use. When integrating, verify that the theoretical forces meet your application's requirements, and account for the cylinder's weight and moving mass in your dynamic calculations. The DSBC-100-125-D3-PPVA-N3 offers a practical combination of performance, standardization, and build quality for engineers seeking a dependable pneumatic actuator.
